• 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.
