18.3.4 Interrupt Request
The maskable external 8 interrupt (P5INT) occurs when each of the Port 5 pins has an interrupt edge.
Figure 18-2 shows the external 8 interrupt (P5INT) generation timing in case P5UD bit of P5CON1 register is “1”.
Figure 18-3 shows the external 8 interrupt (P5INT) generation timing in case P5UD bit of P5CON1 register is “0”.
Note:
- The external 8 interrupt (P5INT) is fixed to both-edge interrupt with sampling.
In STOP mode, since the 16 kHz sampling clock stops, no sampling is performed.
- Depending on the P5n pin state, the External 8 Interrupt Request flag (IRQ2's bit 3) may be set to "1" when the
P5ISEL setting is changed. Therefore, change the P5ISEL setting when the Master Interrupt Enable (MIE) flag is "0",
then reset the External 8 Interrupt Request flag to "0" by software before setting the MIE to "1". For interrupts, see
Chapter 5, "Interrupts."
