A/D Interrupt Enable
Enables ADI interrupt by ADF when this bit is set to 1
A/D Start
Setting this bit to 1 starts A/D conversion. In single
mode, this bit is cleared to 0 automatically when
conversion on the specified channel ends. In scan
mode, conversion continues sequentially on the
specified channels until this bit is cleared to 0 by
software, a reset, or a transition to standby mode or
module stop mode.
Scan Mode
Selects the A/D conversion operating mode.
0: Single mode
1: Scan mode
Clock Select
Sets A/D conversion time.
0: Conversion time is 266 states (max)
1: Conversion time is 134 states (max)
(when the system clock (φ) is 16 MHz or lower)
Switch conversion time while ADST is 0.
When A/D conversion ends in single mode
When A/D conversion ends on all channels
specified in scan mode
When 0 is written after reading ADF = 1
When DTC starts by an ADI interrupt and ADDR is
read
