Many of the GPIO port pins are used as interrupt sources. Some port pins are configured to
generate an interrupt request on either the rising edge or falling edge of the pin input signal.
Other port pin interrupts generate an interrupt when any edge occurs (both rising and
falling). For more information on interrupts using the GPIO pins, see
page 79.
Reading from the Port A-K input data registers (see
from the corresponding port pins. The Port A-K input data registers are Read-only.
PIN[7:0]—Port Input Data
Sampled data from the corresponding port pin input.
0 = Input data is logical 0 (Low).
1 = Input data is logical 1 (High).
