[131] UARTE: EasyDMA transfer size is limited to 255 bytes

This anomaly applies to IC Rev. Engineering A, build codes QIAA-AA0.


DMA transfer is not as long as configured. Only the 8 least significant bits of RXD.MAXCNT and TXD.MAXCNT registers are functional.


RXD.MAXCNT and/or TXD.MAXCNT are configured for DMA transfers > 255 bytes.


EasyDMA transfer sizes longer than 255 bytes are not supported. Larger size values are treated modulo 256.


Split long transfers into chunks of 255 bytes or less.
