| 15 | 0b | RW/L | PM_SYNC Configuration Lock (PM_SYNC_LOCK) The bit is used to lock down the settings of several PM_SYNC-related configuration bits. This bit is self-locking (i.e. once written to '1', it can only be cleared by PLTRST#). |
| 14:12 | - | - | Reserved
|
| 11 | 0b | RW/L | GPIO_D Pin Selection (GPIO_D_SEL) There are two possible GPIOs that can be routed to the GPIO_D PM_SYNC state. This bit selects between them: |
| 10 | 0b | RW/L | GPIO_C Pin Selection (GPIO_C_SEL) There are two possible GPIOs that can be routed to the GPIO_C PM_SYNC state. This bit selects between them: |
| 9 | 0b | RW/L | GPIO_B Pin Selection (GPIO_B_SEL) There are two possible GPIOs that can be routed to the GPIO_B PM_SYNC state. This bit selects between them: |
| 8 | 0b | RW/L | GPIO_A Pin Selection (GPIO_A_SEL) There are two possible GPIOs that can be routed to the GPIO_A PM_SYNC state. This bit selects between them: |
