Note: The KWIEN and KWICR registers do not support read-modify-write operation.
(<KWIEN3:0>) in the KWIEN register are set. The MCU accepts KWI0 to KWI3 inputs as
INT1. The KWI0 to KWI3 pins can be used as external interrupt sources by setting an
interrupt priority level in the <I1M2:0> bits of the INTE1ALM0 register.
Example: To detect a falling edge on key-on wakeup channel 0 to generate an interrupt,
The P50 to P53 pins function as KWI0 to KWI3 when the corresponding bits
