Bit name and function | GPIO3 | GPIO2 | GPIO1 | GPIO0 | PGOODZ_ DCDC1 | PGOODZ_ LDO1 | PB_STAT | |
Default | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 |
Default value loaded by: | UVLO/R | UVLO/R | UVLO/R | UVLO/R | UVLO/R | UVLO/R | UVLO/R | |
Set by: | Rising and falling edge of GPIO3 | Rising and falling edge of GPIO2 | Rising and falling edge of GPIO1 | Rising and falling edge of GPIO0 | Rising edge of PGOODZ_ DCDC1 | Rising edge of PGOODZ_ LDO1 | Rising and falling edge of PB_ STAT | |
Read/write | R | R | R | R | R | R | R | R |
Bit 7..4 | GPIO interrupt register:
0 = GPIO status did not change 1 = GPIO status changed; cleared when read; interrupt not masked in register IRMASK2 |
Bit 3..2 | power good interrupt register:
0 = no interrupt (power good) 1 = interrupt occurred (output voltage of DCDC converter or LDO too low); cleared when read |
Bit 1 | PB_STAT interrupt register:
0 = no interrupt 1 = interrupt occurred; cleared when read; interrupt not masked in register IRMASK2 |
