Description
A/D1 executing A/D conversion or in idle state (Initial value)
[Clearing conditions]
1. Read ADF when ADF =1, then write 0 in ADF
2. DMAC activated by ADI1 interrupt
A/D1 has ended A/D conversion and digital value has been
transferred to ADDR
[Setting conditions]
1. Single mode: A/D conversion ends
2. Scan mode: All A/D conversion ends within one selected
ADI1 A/D interrupt is disabled
ADI1 A/D interrupt is enabled
A/D conversion is stopped
A/D conversion is in progress
[Clearing conditions]
1. Single mode: ADST is cleared automatically when A/D
2. Scan mode: Confirm that ADF in ADCSR1 is 1, then write 0
