Bit | Field | Type | Reset | Description |
---|---|---|---|---|
7 | RSVD | R | 1b | Reads return 1b. |
6 | SEQ_STATUS | R | 0b | Status of the channel sequencer. 0b = Sequence stopped 1b = Sequence in progress |
5-3 | RESERVED | R | 0b | Reserved. Reads return 010b. |
2 | CRCERR_FUSE | R | 0b | Device power-up configuration CRC check status. To
re-evaluate this bit, software reset the device or power cycle AVDD.
0b = No problems detected in power-up configuration. 1b = Device configuration not loaded correctly. |
1 | CRCERR_IN | R/W | 0b | Status of CRC check on incoming data. Write 1b to
clear this error flag. 0b = No CRC error. 1b = CRC error detected. All register writes, except to addresses 0x00 and 0x01, are blocked. |
0 | BOR | R/W | 1b | Brown out reset indicator. This bit is set if brown
out condition occurs or device is power cycled. Write 1b to this bit
to clear the flag. 0b = No brown out from the last time this bit was cleared. 1b = Brown out condition detected or device power cycled. |
