PRODUCTION DATA
From SLEEP mode, either a WAKE or SLEEPtoACTIVE ping/tone can put the device in ACTIVE mode. A WAKE ping/tone will generate a digital reset to the device. Because the LDO supplies remain on during SLEEP mode, only the FAULT_SYS[DRST] = 1 is set, indicating a digital reset has occurred. Certain expected faults related to being reset are set. See SHUTDOWN mode for detail. Registers are reset to default, the OTP shadow registers are reloaded with the OTP programmed values.
If a SLEEPtoACTIVE ping/tone is used to wake up the device from SLEEP mode to ACTIVE mode, device will simply enter ACTIVE mode without digital resetting but the UART engine will be reset. Hence, in the base device, the FAULT_COMM1[COMMCLR_DET] = 1 and host clears it after entering ACTIVE mode.
