Description
SPI_EN
Open (Default)
I
2
C Mode. The signal path for I
2
C communication between the MCU
and the PMIC is enabled.
Closed
SPI mode. The signal path for SPI communication between the MCU
and the PMIC is enabled.
TRIG_WDG, GPIO2, SDA2/SDO Open
GPIO mode. GPIO2 from PMIC is connected to PM7 of the MCU
through a level translator.
TRIG_WDG, GPIO2: Closed
Trigger Watchdog mode. GPIO2 of the PMIC should be in the
Alternative function to support the watchdog trigger input signal.
GPIO2 from the PMIC is connected to the MCU output and
TRIG_WDG.
GPIO2,SDA2/SDO: Closed
(Default)
I
2
C Mode (J7 VIO_IN, I2C/SPI:
Open)
Q&A Watchdog mode. GPIO2 of
the PMIC should be in the
Alternative function to support the
Q&A Watchdog and the I
2
C mode
is selected. This setting is done in
conjunction with J15,
GPIO1,SCL2/CS: Closed.
SPI mode (J7 VIO_IN, I2C/SPI:
Closed)
SPI mode, Chip Select. GPIO2 of
the PMIC should be in the
Alternative function to support
SPI communication. This setting
is done in conjunction with J15,
GPIO1, SCL2/CS: Closed.
ERR_SoC, GPIO3
Open (Default)
GPIO mode. GPIO3 of the PMIC is connected to PP5 of the through
a level translator.
Closed
SoC Error Count Down mode. GPIO3 of the PMIC should be in the
Alternative function to support the system error count down from the
SoC. GPIO is connected to alternative MCU output, nERR_SoC.
ERR_MCU, GPIO7
Open (Default)
GPIO mode. GPIO7 of the PMIC is connected to POH of the through
a level translator.
Closed
MCU Error Count Down mode. GPIO7 of the PMIC should be in the
Alternative function to support the system error count down from the
MCU. GPIO7 is connected to MCU output PK5, nERR_MCU.
TRIG_WDG, GPIO11
Open (Default)
GPIO mode. GPIO11 from PMIC is connected to PP4 of the MCU
through a level translator.
Closed
Trigger Watchdog mode. GPIO11 of the PMIC should be in the
Alternative function to support the watchdog trigger input signal.
GPIO11 from the PMIC is connected to the MCU output PK4,
TRIG_WDG.
