Description
Timer Trigger Select 1 and 0
These bits 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 external trigger from TPU is
10: A/D conversion start by external trigger from TMR is
11: A/D conversion start by the ADTRG0 pin is enabled*
Scan Mode
These bits select the A/D conversion operating mode.
0X: Single mode
10: Scan mode. A/D conversion is performed
11: Scan mode. A/D conversion is performed
Clock Select 1 and 0
These bits set the A/D conversion time. Set bits CKS1
and CKS0 only while A/D 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)
