GPIOx Output Driver Type
x0 = Open Drain
x1 = CMOS
GPIOx Direction Configuration
x0 = Output (Type selected by Bit 0)
x1 = Input (Bit 0 is ignored)
The value in the DATA_IN bit reflects the electrical state of the GPIOx pin at the time the register read was initiated. When
Bit 1, DIRECTION, is 0 (Output Mode), the contents of this register are not required to be updated on reads and is assumed
to be invalid by the system controller. The PMIC should de-bounce the inputs over 1-10 ms to insure a clean transition.
X0 = Electrical Low
x1 = Electrical High
The value in the DATA_OUT bit reflects the desired electrical output state of the GPIOx pin. When Bit 1, DIRECTION, is 1
(Input Mode), the contents of this register may still be read or written, but will not be reflected until the GPIOx is reverted
to an output (Bit 1, DIRECTION, is 0)
x0 = Electrical Low
x1 = Electrical High (CMOS) or High-impedance Output (Open-Drain)
These bits set the interrupt definition. The MASK (00) determines if the corresponding interrupt flag bit is set or not on an
interrupt. The other logic levels will set the corresponding interrupt flag bit in the register upon the specific edge detection
defined by the level. They will also set bit 4 of the 1st level INTERRUPT register, see section Interrupt Controller for more
details.
x0 = Mask.
x1 = Negative Edge
x2 = Positive Edge
x3 = Both Edges
These bits set the debounce time on the GPIOx when configured as inputs
x0 = No Debounce
x1 = 10 ms
x2 = 20 ms
x3 = 30 ms
GPIO0 Interrupt Flag
x0 = No Interrupt occurred or Masked Interrupt
x1 = Interrupt occurred
GPIO1 Interrupt Flag
x0 = No Interrupt occurred or Masked Interrupt
x1 = Interrupt occurred
GPIO2 Interrupt Flag
x0 = No Interrupt occurred or Masked Interrupt
x1 = Interrupt occurred
GPIO3 Interrupt Flag
x0 = No Interrupt occurred or Masked Interrupt
x1 = Interrupt occurred
