PRODUCTION DATA
Communication is not supported in SHUTDOWN mode, host must send a WAKE ping or WAKE tone to enter ACTIVE mode. Once device transitions from SHUTDOWN mode to ACTIVE mode, the following table indicates the expected fault bits being set under such transition has occurred.
Device Position In The Daisy Chain | Expected Fault Bits After Waking Up From SHUTDOWN | |
---|---|---|
Base device | FAULT_SYS[DRST] = 1 | Digital reset by the wake ping |
FAULT_COMM3[FCOMM_DET] = 1 | [DRST] = 1 from the upper device | |
FAULT_COMM1[COMMCLR_DET] = 1 | UART engine is reset | |
Stack device (except top of stack) | FAULT_SYS[DRST] = 1 | Digital reset by the wake tone |
FAULT_COMM3[FCOMM_DET] = 1 | [DRST] = 1 from the upper device | |
Top of stack device | FAULT_SYS[DRST] = 1 | Digital reset by the wake tone |
