Section 14 A/D Converter
Bit 7—A/D End Flag (ADF): ADF indicates that A/D conversion is completed.
Bit 7 (ADF)
0
1
Bit 6—A/D Interrupt Enable (ADIE): ADIE selects whether or not an A/D interrupt (ADI) is
requested when A/D conversion is completed.
Bit 6 (ADIE)
0
1
Bit 5—A/D Start (ADST): ADST selects the start or halting of A/D conversion. Whenever the
A/D converter is operating, this bit is set to 1. It can also be set to 1 by the A/D conversion trigger
input pin (ADTRG).
Bit 5 (ADST)
0
1
Bit 4—Scan Mode (SCAN): SCAN selects either scan mode or single mode for operation. See
section 14.4, Operation, for descriptions of these modes. The mode should be changed only when
the ADST bit is cleared to 0.
Bit 4 (SCAN)
0
1

REJ09B0272-0700
Description
Cleared to 0 under the following conditions:
Set to 1 at the following times:
Description
The A/D interrupt (ADI) request is disabled
The A/D interrupt (ADI) request is enabled
Description
A/D conversion is halted
Description
Single mode
Scan mode
The CPU reads the ADF bit while the bit is set to 1, then writes 0 in the bit
The ADI starts the DMAC and the A/D conversion register is accessed
Single mode: When A/D conversion is complete
Scan mode: When A/D conversion of all selected channels is complete
Single mode: A/D conversion is performed. This bit is automatically cleared
to 0 at the end of the conversion.
Scan mode: A/D conversion starts and continues cyclically on the selected
channels until this bit is cleared to 0 by software, a reset, or standby mode.
