Wakeup Function:
Detects the falling edge of wakeup input signals and sets the wakeup interrupt request
flag (IFWU: $003, bit 2). Refer to figure 12 for a block diagram showing the wakeup interrupt. The wakeup
select register (WSR: $018) can select from one to eight wakeup inputs (

) (figure 13). The
wakeup function can operate in any mode other than stop mode. When the wakeup interrupt is received, the
CPU generates an independent vector address ($000E).
Note:
The wakeup select register (WSR: $018) controls whether the wakeup input is to be valid or
invalid, but it can not switch the pin inputs between the R ports and wakeup. When using the pins
only as R ports, nullify wakeup input or set the wakeup interrupt mask (IMWU: $003, bit 3).
