6 Multiplexed Input Channels

The SH79F082 include a single ended, 10-bit SAR Analog to Digital Converter (ADC) with build in reference voltage

connected to the VDD, users also can select the VREF pin input reference voltage. The 6 ADC channels are shared with 1 ADC

module; each channel can be programmed to connect with the analog input individually. Only one channel can be available

at one time. GO/DONE

————

signal is available to start convert, and indicate end of convert. When conversion is completed, the

data in AD convert data register will be updated and ADCIF bit in ADCON register will be set. If ADC Interrupt is enabled, the

ADC interrupt will generate.

The ADC integrates a digital compare function to compare the value of analog input with the digital value in the AD converter.

If this function is enabled (set EC bit in ADCON register) and ADC module is enabled (set ADON bit in ADCON register).

When the corresponding digital value of analog input is larger than the value in compare value register (ADDH/L), the ADC

interrupt will occur, otherwise no interrupt will be generated. The digital comparator can work continuously when GO/DONE

————

bit is set until software clear, which behaviors different with the AD converter operation mode.

The ADC module including digital compare module can wok in Idle mode and the ADC interrupt will wake up the Idle mode,

but is disabled in Power-Down mode.
