IOCC (PORTC I/O control, ADC control)
PAGE0 (Unused)
** Bit0 , Bit3 ~ Bit7 must clear to 0 or MCU power consumption will increase.
The default value in these 6 un-define bits are “1”. Please clear them to “0” when init MCU.
PAGE1 (PORT switch)
IOCD (Clock source, Prescaler of CN1 and CN2)
PAGE0 (Reserved)
PAGE1 (Clock source and prescaler for COUNTER1 and COUNTER2)

Bit 1 ~ Bit 2 (IOCC1 ~ IOCC2) : PORTC(1~2) I/O direction control register
Bit 0(MS) : P6* switch mode selection
Bit 1 ~ Bit 7: (undefined) not allowed to use
Bit 0 ~ Bit 2 (C1_PSC0 ~ C1_PSC2) : COUNTER1 prescaler ratio
Bit 4 ~ Bit 6 (C2_PSC0 ~ C2_PSC2) : COUNTER2 prescaler ratio
