Start Condition

• When the ADCAP bit is set to “0” (software trigger),

set the ADST bit to “1” (A-D conversion starts)

• When the ADCAP bit is set to “1” (capture),

Timer Z interrupt request is generated while the ADST bit is set to “1”

Stop Condition

• A/D conversion completes (ADST bit is set to “0”)

• Set the ADST bit to “0”

Interrupt Request

Generation Timing

A/D conversion completes

Input Pin

Select one of AN8 to AN11

Reading of A/D Conversion

Result

Read AD register
