ADCSR is an 8-bit readable/writable register that selects the mode and controls the A/D converter.
ADCSR is initialized to H'00 by a reset and in standby mode.
Bit 7—A/D End Flag (ADF): Indicates the end of A/D conversion.
Bit 7: ADF
Description
0
[Clearing conditions]
(Initial value)
(1) Cleared by reading ADF while ADF = 1, then writing 0 to ADF
(2) Cleared when DMAC is activated by ADI interrupt and ADDR is read
1
[Setting conditions]
(1) Single mode: A/D conversion ends
(2) Multi mode: A/D conversion ends on all selected channels
(3) Scan mode: A/D conversion ends on all selected channels
Bit 6—A/D Interrupt Enable (ADIE): Enables or disables the interrupt (ADI) requested at the
end of A/D conversion. The ADIE bit should be set while the A/D conversion stops.
Bit 6: ADIE
Description
0
A/D end interrupt request (ADI) is disabled
(Initial value)
1
A/D end interrupt request (ADI) is enabled
