Bit 6—A/D Interrupt Enable (ADIE): Enables or disables the interrupt (ADI) requested at the

end of A/D conversion.

Bit 6

ADIE

Description

A/D end interrupt request (ADI) is disabled

(Initial value)

A/D end interrupt request (ADI) is enabled

Bit 5—A/D Start (ADST): Starts or stops A/D conversion. The ADST bit remains set to 1 during

A/D conversion. It can also be set to 1 by external trigger input at the

ADTRG pin, or by an 8-bit

timer compare match.

Bit 5

ADST

Description

A/D conversion is stopped

(Initial value)

• Single mode: A/D conversion starts; ADST is automatically cleared to 0 when

conversion ends.

• Scan mode: A/D conversion starts and continues, cycling among the selected

channels, until ADST is cleared to 0 by software, by a reset, or by a transition to

standby mode.

Bit 4—Scan Mode (SCAN): Selects single mode or scan mode. For further information on

operation in these modes, see section 15.4, Operation. Clear the ADST bit to 0 before switching

the conversion mode.

Bit 4

SCAN

Description

Single mode

(Initial value)

Scan mode

Bit 3—Clock Select (CKS): Selects the A/D conversion time. Clear the ADST bit to 0 before

switching the conversion time.

Bit 3

CKS

Description

Conversion time = 134 states (maximum)

(Initial value)

Conversion time = 70 states (maximum)
