PRODUCTION DATA.
Programmable Power Good delay for GPO1, GPO2, and GPO4 pins, measured from the moment when all VRs assigned to respective GPO reach their regulation range to Power Good assertion. This is an optional register as the PMIC can be programmed for system PG, level shifter or I2C controller GPO.

---|---|---|---|---|
7:5 | GPO2_PG_DELAY[2:0] | R/W | X | Programmable delay Power Good or level shifter for GPO2 pin. Measured from the moment when all rails grouped to this pin reach their regulation range. All values have ±10% variation.
000: 0 ms 001: 5.0 ms 010: 10 ms 011: 15 ms 100: 20 ms 101: 50 ms 110: 75 ms 111: 100 ms —: Bits not used. If GPO2 is controlled by I2C rather than PG and is not used internally for VTT LDO enable, these bits have no impact. Default is set to 0b. |
4:2 | GPO4_PG_DELAY[2:0] | R/W | X | Programmable delay Power Good or level shifter for GPO4 pin. Measured from the moment when all rails grouped to this pin reach their regulation range. All values have ±10% variation.
000: 0 ms 001: 5.0 ms 010: 10 ms 011: 15 ms 100: 20 ms 101: 50 ms 110: 75 ms 111: 100 ms —: Bits not used. If GPO4 is controlled by I2C rather than PG, these bits have no impact. Default is set to 0b. |
1:0 | GPO1_PG_DELAY[1:0] | R/W | X | Programmable delay Power Good or level shifter for GPO1 pin. Measured from the moment when all rails grouped to this pin reach their regulation range. All values have ±10% variation.
00: 0 ms 01: 5.0 ms 10: 10 ms 11: 15 ms —: Bits not used. If GPO1 is controlled by I2C rather than PG, these bits have no impact. Default is set to 0b. |
