GPIO[7:0] Negative Edge Interrupt Trigger
This bit determines whether the associated GPIO interrupt is triggered on the negative
edge (when the GPIOx pin changes from 1 to 0).
When this bit = 0, the associated GPIOx interrupt (GPIO_INT) is not triggered on the neg-
ative edge.
When this bit = 1, the associated GPIOx interrupt (GPIO_INT) is triggered on the negative
edge.
GPIO[7:0] Interrupt Status
If GPIOs are configured to generate an Interrupt (see REG[5Eh] and REG[60h]), these
status bits will indicate which GPIO generated the interrupt.
To clear the corresponding GPIO[7:0] Interrupt Status bit, write a 1b then a 0b to the bit.
GPIO[7:0] Pull-down Control
All GPIO[7:0] pins have internal pull-down resistors. These bits individually control the
state of the corresponding pull-down resistor.
When the bit = 0, the pull-down resistor for the corresponding GPIO pin is inactive.
When the bit = 1, the pull-down resistor for the corresponding GPIO pin is active.
