Description
State Control
Sets the A/D conversion time in combination with the
CKSL1 and CKSL0 bits.
0: 50 states
1: 64 states
When changing the A/D conversion time, first clear the
ADST bit to 0.
Clock Select 1 and 0
Select the A/D conversion time.
00: Pφ/4
01: Pφ/3
10: Pφ/2
11: Pφ
When changing the A/D conversion time, first clear the
ADST bit to 0.
CKSL[1:0] = B'11 can be set while Pφ ≤ 25 MHz.
A/D Mode 1 and 0
Select the A/D conversion mode.
00: Single mode
01: 4-channel scan mode
10: Setting prohibited
11: 2-channel scan mode
When changing the operating mode, first clear the
ADST bit to 0.
A/D Continuous Scan
Selects either single-cycle scan or continuous scan in
scan mode. This bit is valid only when scan mode is
selected.
0: Single-cycle scan
1: Continuous scan
When changing the operating mode, first clear the
ADST bit to 0.
