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

• When the DMAC is 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

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, or timer conversion start triggers.

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.
