• Bit 7—A/D End Flag (ADF): This status flag indicates that A/D conversion has ended.

Bit 7: ADF

Description

Clear conditions

(Initial value)

With ADF = 1, by reading the ADF flag then writing 0 in ADF

Set conditions

• Single mode: When A/D conversion ends after conversion for all

designated channels

• 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.

Bit 6: ADIE

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.

The ADST bit remains set to 1 during A/D conversion. It can also be set to 1 by MTU trigger

input.

Bit 5: ADST

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, and by power-on reset.

• Bit 4—Scan Mode (SCAN): Selects single mode or scan mode for A/D conversion. For details

of the operation in single mode and scan mode, see section 13.4, Operation. Change the mode

only when ADST = 0.
