Description
Timer Trigger Select 1 and 0
Select enabling or disabling of the start of A/D
conversion by a trigger signal.
00: A/D conversion start by external trigger is
disabled
01: A/D conversion start by conversion start trigger
(TPU) is enabled
10: A/D conversion start by conversion start trigger
(TMR) is enabled
11: A/D conversion start by ADTRG pin is enabled
Scan Mode
Select single mode or scan mode as the A/D
conversion operating mode.
0x: Single mode
10: Scan mode. A/D conversion is performed
continuously for channels 1 to 4
11: Scan mode. A/D conversion is performed
continuously for channels 1 to 8.
Clock Select 1 and 0
Set the A/D conversion time.
Only set bits CKS1 and CKS0 while conversion is
stopped (ADST = 0).
00: A/D conversion time = 530 states (max.)
01: A/D conversion time = 266 states (max.)
10: A/D conversion time = 134 states (max.)
11: A/D conversion time = 68 states (max.)
Reserved
These bits are always read as 0 and cannot be
modified.
