ADC_POWER SPEED1 SPEED0 ADC_FLAG ADC_START

CHS2 CHS1 CHS0

ADC_POWER : When clear, shut down the power of ADC bolck. When set, turn on the power of ADC block.

ADC_FLAG : ADC interrupt flag.It will be set by the device after the device has finished a conversion, and

should be cleared by the user's software.

ADC_STRAT : ADC start bit, which enable ADC conversion.It will automatically cleared by the device after the

device has finished the conversion

EX0

EA : disables all interrupts.

If EA = 0,no interrupt will be acknowledged.

If EA = 1, each interrupt source is individually enabled or disabled by setting or clearing its enable bit.

EADC_SPI : Interrupt controller of Serial Peripheral Interface (SPI) and A/D Converter (ADC).

If EADC_SPI = 0, Disable the interrupt of Serial Peripheral Interface (SPI) and A/D Converter (ADC).

If EADC_SPI = 1, Enable the interrupt of Serial Peripheral Interface (SPI) and A/D Converter (ADC).

CF : PCA Counter Overflow flag. Set by hardware when the counter rolls over. CF flags an interrupt if bit ECF

in CMOD is set. CF may be set by either hardware or software but can only be cleared by software.

CR : PCA Counter Run control bit. Set by software to turn the PCA counter on. Must be cleared by software to

turn the PCA counter off.

CCF3: PCA Module 3 interrupt flag. Set by hardware when a match or capture occurs. Must be cleared by

software.

CCF2: PCA Module 2 interrupt flag. Set by hardware when a match or capture occurs. Must be cleared by

software.

CCF1: PCA Module 1 interrupt flag. Set by hardware when a match or capture occurs. Must be cleared by

software.

CCF0: PCA Module 0 interrupt flag. Set by hardware when a match or capture occurs. Must be cleared by

software.
