Analog-to-Digital Converter (ADC)
CH[4:0] — ADC Channel Select Bits
3.7.2 ADC Data Register
One 8-bit result register is provided. This register is updated each time an ADC conversion completes.
44
CH4, CH3, CH2, CH1, and CH0 form a 5-bit field which is used to select one of the four ADC channels.
The five select bits are detailed in
analog and a digital input simultaneously to prevent switching noise from corrupting the analog signal.
The ADC subsystem is turned off when the channel select bits are all set to 1. This feature allows for
reduced power consumption for the MCU when the ADC is not used. Reset sets all of these bits to a 1.
Address: $003E
Recovery from the disabled state requires one conversion cycle to stabilize.
