Bit 4: P14/IRQ4 pin function switch (IRQC4)

This bit selects whether pin P14/IRQ4 is used as P14 or as IRQ4.

Bit 4

IRQC4

Explanation

0P14/IRQ4 pin functions as P14.

(initial value)

1P14/IRQ4 pin functions for IRQ4* input.

Note: * Rising or falling edge sensing can be designated for pin IRQ4.

For details see 3.2.3 (2), IRQ edge select register (IEGR).

Bits 3 and 2: Reserved bits

Bits 3 and 2 are reserved; they always read 1, and cannot be modified.

Bit 1: P11/IRQ1 pin function switch (IRQC1)

This bit selects whether pin P11/IRQ1 is used as P11 or as IRQ1.

Bit 1

IRQC1

Explanation

0P11/IRQ1 pin functions as P11.

(initial value)

1P11/IRQ1 pin functions for IRQ1* input.

Note: * Rising or falling edge sensing can be designated for pin IRQ1.

For details see 3.2.3 (2), IRQ edge select register (IEGR).

Bit 0: P10/IRQ0 pin function switch (IRQC0)

This bit selects whether pin P10/IRQ0 is used as P10 or as IRQ0.

Bit 0

IRQC0

Explanation

0P10/IRQ0 pin functions as P10.

(initial value)

1P10/IRQ0 pin functions for IRQ0* input.

Note: * Rising or falling edge sensing can be designated for pin IRQ0.

For details see 3.2.3 (2), IRQ edge select register (IEGR).
