The QSPI peripheral provides support for communicating with an external flash memory device using SPI.
The main features for the QSPI peripheral are:
Before any data can be transferred to or from the external flash memory, the peripheral needs to be configured.
If the IFCONFIG0 register is configured to use the quad mode, the external flash device also needs to be set in the quad mode before any data transfers can take place.
This can be done by sending custom instructions to the external flash device, as described in Sending custom instructions.
A write operation to the external flash is configured using the WRITE.DST, WRITE.SRC, and WRITE.CNT registers. It is started using the WRITESTART task.
The READY event is generated when the transfer is complete.
The QSPI peripheral automatically takes care of splitting DMA transfers into page writes.
Erase of pages/blocks of the external flash is configured using the ERASE.PTR and ERASE.LEN registers. It is started using the ERASESTART task.
The READY event is generated when the erase operation has been started.
In this case, the READY event will not indicate that the erase operation of the flash has been completed, but it only signals that the erase operation has been started. The actual status of the erase operation can normally be read from the external flash using a custom instruction (see Sending custom instructions).
Execute in place (XIP) allows the CPU to execute program code directly from the external flash.
After the external flash has been configured, the CPU can execute code from the external flash by accessing the XIP memory region. See the following figure and Memory for details.
The XIP memory region is read-only, writing to it will result in a bus error.
When accessing the XIP memory region, the start address of this XIP memory region will map to the address XIPOFFSET of the external flash.
The contents of an external flash memory can be protected using stream cipher encryption. Encryption can be configured and enabled independently for XIP and EasyDMA, with separate keys and nonce.
Once configured and enabled, the stream cipher operates between the AHB bus and the external flash, encrypting and decrypting data passing through.
The same nonce and key must be used for both encryption and decryption of the same memory address.
The memory address used for encryption is the external flash memory address and thus independent of XIPOFFSET. This means a second firmware image can be encrypted and written using EasyDMA, then XIPOFFSET set to point to the new firmware image before executing from it.
Stream ciphers are symmetric. They do not differentiate between encrypting or decrypting, reading or writing. Thus, if the contents of a plain text external flash is read when stream cipher is enabled, the data provided to the MCU is encrypted.
Custom instructions can be sent to the external flash using the CINSTRCONF, CINSTRDAT0, and CINSTRDAT1 registers. It is possible to send an instruction consisting of a one-byte opcode and up to 8 bytes of additional data and to read its response.
A custom instruction is prepared by first writing the data to be sent to CINSTRDAT0 and CINSTRDAT1 before writing the opcode and other configurations to the CINSTRCONF register.
The custom instruction is sent when the CINSTRCONF register is written and it is always sent on a single data line SPI interface.
The READY event will be generated when the custom instruction has been sent.
After a custom instruction has been sent, the CINSTRDAT0 and CINSTRDAT1 will contain the response bytes from the custom instruction.
The data of custom instructions is not part of the stream cipher encryption.
The LFEN and LFSTOP fields in the CINSTRCONF register control the operation of the custom instruction Long frame mode. Long frame mode is a mechanism that permits arbitrary byte length custom instructions. While in Long frame mode a long custom instruction sequence is split in multiple writes to the CINSTRDAT0 and CINSTRDAT1 registers.
To enable Long frame mode every write to the CINSTRCONF register must have the LFEN field set to 1
. The contents
of the OPCODE field will be transmitted after the first write to CINSTRCONF and will be omitted in every subsequent write to
this register. For subsequent writes the number of data bytes as specified in the LENGTH field
are transferred (that is the value of LENGTH - 1 data bytes). The values of the LIO2 and LIO3 fields are
set in the first write to CINSTRCONF and will apply for
the entire custom instruction transmission until the long frame is finalized.
To finalize a long frame transmission, the LFSTOP field in the CINSTRCONF register must be set to 1
in the last write to this
register.
The external flash memory can be put in Deep power-down mode (DPM) to minimize its current consumption when there is no need to access the memory.
DPM is enabled in register IFCONFIG0 and configured in register DPMDUR. The DPM status of the external memory can be read in the STATUS register. The DPMDUR register has to be configured according to the external flash specification to get the information in the STATUS register and the timing of the READY event correct.
Entering or exiting DPM is controlled using register IFCONFIG1.

RXDELAY |
[7..0] |
Timing related to sampling of the input serial data. The value of RXDELAY specifies the number of prescaled 192 MHz cycles delay from the the rising edge of the SPI Clock (SCK) until the input serial data is sampled. For example, if RXDELAY is set to 0, the input serial data is sampled on the rising edge of SCK. |
