Figure 3.7 shows the procedure for setting a bit in a port mode register and clearing the interrupt
request flag.
When switching a pin function, mask the interrupt before setting the bit in the port mode register
(or AEGSR). After accessing the port mode register (or AEGSR), execute at least one instruction
(e.g., NOP), then clear the interrupt request flag from 1 to 0. If the instruction to clear the flag is
executed immediately after the port mode register (or AEGSR) access without executing an
intervening instruction, the flag will not be cleared.
