This anomaly applies to IC Rev. Engineering C, build codes CKAA-CA0, QIAA-CA0.
Device does not start up in high voltage mode.
Using REG0 and external circuitry supply or slow rise time on VDDH. Power on reset (POR) may not release correctly.
Device does not start up when it should.
Do not draw current from VDD pin (external circuitry supply) during power up and ensure VDDH rise time to 3 V is below 1 ms.
