• Bit 7—A/D End Flag (ADF): This status flag indicates that A/D conversion has ended.
Bit 7: ADF
0
1
Description
Clear conditions (initial value)
• With ADF = 1, by reading the ADF flag then writing 0 in ADF
• When the DTC or DMAC are activated by an ADI interrupt
Set conditions
• Single mode: When A/D conversion ends after conversion for all
designated channels (during buffer operation, this is not set until
operation of the specified buffer has ended)
• Scan mode: After one round of A/D conversion for all specified
channels
• Bit 6—A/D Interrupt Enable (ADIE): Enables or disables interrupt requests (ADI) after A/D
conversion ends. Set the ADIE bit while conversion is suspended.
Bit 6: ADIE
0
1
Description
Disables interrupt requests (ADI) after A/D conversion ends (initial
value)
Enables interrupt requests (ADI) after A/D conversion ends
• Bit 5—A/D Start (ADST): Selects start or stop for A/D conversion. A 1 is maintained during
A/D conversions.
The ADST bit can be set to 1 by software, timer conversion start triggers, or an A/D external
trigger input pin (ADTRG).
Bit 5: ADST
0
1
Description
A/D conversion halted (initial value)
Single mode: Start A/D conversion. Automatically cleared to 0 after
conversion for the designated channel ends.
Scan mode: Start A/D conversion. Continuous conversion until 0
cleared by software.
