• Bit 4—Clock Select (CKS): Sets the A/D conversion time. Set, according to the operating

frequency, to give a conversion time of at least 2 µs (5 V version) or 4 µs (3.3 V version).

Make conversion time changes only while conversion is halted.

Bit 4: CKS

Description

Conversion time = 40 states (A/D converter standard clock =

φ/2) (initial

value)

Conversion time = 80 states (when

φ/4 is selected)

• Bit 3—Group Mode (GRP): Designates either select mode or group mode for the A/D

conversion channel selection.

Set the GRP bit only while conversion is halted.

Bit 3: GRP

Description

Select mode (initial value)

Group mode

• Bits 2–0—Channel Select 2–0 (CH2–CH0): These bits, along with the GRP bit, select the

analog input channel.

Set the input channel only while conversion is halted.
