4.2.12 IOCF0/IMR (Interrupt Mask Register)
Registers of IOC Page 1 (IOC61 ~ IOCE1, Bit 0 of R5 = “1”)
4.2.13 IOC61/WUCR (Wake Up and sink current of P5.7/IROUT Control
4.2.14 IOC71/TCCCR (TCC Control Register)
Bit 7~Bit 0: interrupt enable bit. Enable interrupt source respectively.
IOCF0 register is readable and writable.
Bit 7: IROCS: IROUT/PORT5.7 output sink current set
Bit 6,5,4: Not used
Bit 3 (/WUE8H): 0/1=> enable/disable P8.4~P8.7 pin change wake up function
Bit 2 (/WUE8L): 0/1=> enable/disable P8.0~P8.3 pin change wake up function
Bit 1 (/WUE6H): 0/1=> enable/disable P6.4~P6.7 pin change wake up function
Bit 0 (/WUE6L): 0/1=> enable/disable P6.0~P6.3 pin change wake up function

Port 6 and Port 8 must avoid input floating when wakeup function is enabled.
The initial state of wakeup function is enabled.
