Bit 5âA/D Start (ADST): Selects starting or stopping on A/D conversion. Holds a value of 1
during A/D conversion.
The ADST bit can be set to 1 by software, a timer conversion start trigger, or the A/D external
trigger input pin (ADTRG).

0
1
Description
⢠A/D conversion stopped
(Initial value)
⢠Single mode: A/D conversion is started. Cleared to 0 automatically when
conversion on the specified channel ends
⢠Scan mode: A/D conversion is started. Conversion continues sequentially on the
selected channels until ADST is cleared to 0 by software, a reset, or
a transition to standby mode or module stop mode
Bit 4âScan Mode (SCAN): Selects single mode or scan mode as the A/D conversion operating
mode. See section 19.4, Operation, for single mode and scan mode operation. Only set the SCAN
bit while conversion is stopped (ADST = 0).

Bit 3âChannel Select 3 (CH3): Switches the analog input pins assigned to group 0 or group 1.
Setting CH3 to CH1 enables AN8 to AN15 to be used instead of AN0 to AN7.
Bit 3
CH3
0
1
Description
AN8 to AN11 are group 0 analog input pins, AN12 to AN15 are group 1 analog input
pins
AN0 to AN3 are group 0 analog input pins, AN4 to AN7 are group 1 analog input pins
(Initial value)
