Bit | Field | Access | Reset | Description |
---|---|---|---|---|
15 | PEC | RW | NVM | 0b: PEC Optional. Transactions received without PEC byte will be processed. 1b: PEC Required. Transactions received without PEC byte will be rejected as invalid PEC. |
14 | RESET_CNT | RW | NVM | 0b: VOUT_COMMAND will be unchanged following a shutdown. 1b: VOUT_COMMAND will be changed to VBOOT on a Control or OPERATION shutdown. |
13 | RESET_FLT | RW | NVM | 0b: VOUT_COMMAND will be unchanged following a Fault Restart. 1b: VOUT_COMMAND will be changed to VBOOT on Restart from a Fault when Fault Retry is set to Retry after Fault. |
12 | RESET# | RW | NVM | Sets the function of the PGD/RST pin. 0b: PGD/RST functions as PGOOD and internal pullup is disabled. 1b: PGD/RST functions as RESET# and internal pullup is set by bit 3 PULLUP#. |
11:3 | Reserved | RW | NVM | Reserved. Must be 000000000b |
3 | PULLUP# | RW | NVM | Sets the pullup of the PGD/RST pin when RESET# = 1b. 0b: Internal pullup of PGD/RST pin enabled when RESET# = 1b. 1b: Internal pullup of PGD/RESET_B pin disabled when RESET# = 1b. |
2 | FLT_CNT | RW | NVM | 0b: Fault Counter counts down one cycle on PWM cycle without fault 1b: Fault Counter resets counter to 0 on PWM cycle without fault |
1:0 | ADC_RES | RW | NVM | ADC Resolution Control 00b: Set ADC Resolution to 12-bit 01b: Set ADC Resolution to 10-bit 10b: Set ADC Resolution to 8-bit 11b: Set ADC Resolution to 6-bit |
