GPIO12 alternate function:
Input:
0000 = GPIO
0001 = CHIP_RESET
Output:
0000 = GPIO
0001 = ISINKE
0010 = LINE_GT_BATT
0011 = LINE_SW
0100 = 32kHz
Reset by state machine. Default held in metal mask.
0011 = /BATT_FAULT
0100 = /MEMRST
Reset by state machine. Default held in metal mask.
GPIO8 alternate function:
Input:
0000 = GPIO
0001 = /MR
0010 = ADCBCLK
0011 = PWR_OFF
0100 = HIBERNATE (edge)
Output:
0000 = GPIO
0001 = /VCC_FAULT
0010 = ADCBCLK
0011 = /BATT_FAULT
0100 = /RST
Reset by state machine. Default held in metal mask.
AUXADC control
0 = disabled
1 = enabled
Reset by state machine.
Continuous conversion mode:
0 = Polling mode
1 = Continuous mode
Reset by state machine.
Writing “1” initiates a set of measurements in
polling mode (AUXADC_CTC=0). This bit is
automatically reset after the measurements are
completed.
Reset by state machine.
