Bit 6(PLLEN) : PLL's power control bit which is CPU mode control register
0/1
disable PLL/enable PLL
If enable PLL, CPU will operate at normal mode (high frequency). Otherwise, it will run at green mode
(low frequency, 32768 Hz).

Bit 7(IDLE) : Sleep mode or IDLE mode control after using "SLEP" instruction.
0/1
SLEEP mode/IDLE mode.
This bit will decide SLEP instruction which mode to go.
The status after wake-up and the wake-up sources list as the table below.

bit4 or bit5 or bit6 = 1
PORT7(0~3)
IOCF bit3 or bit4 or
bit5 or bit7=1
<Note> PORT70 's wakeup function is controlled by IOCF bit 3. It's falling edge or rising edge trigger
(controlled by CONT register bit7).
PORT7(1~3) 's wakeup functions are controlled by IOCF bit (4,5,7). They are falling edge trigger.
PORT80~PORT83’s wakeup function are controlled by RE PAGE0 bit 0 ~ bit 3. They are falling
edge trigger.
