ADCR is an 8-bit readable/writable register that enables or disables external triggering of A/D
conversion operations and sets the A/D conversion time.
ADCR is initialized to H'33 by a reset, and in standby mode or module stop mode.
Bits 7 and 6—Timer Trigger Select 1 and 0 (TRGS1, TRGS0): Select enabling or disabling of
the start of A/D conversion by a trigger signal. Only set bits TRGS1 and TRGS0 while conversion
is stopped (ADST = 0).

Bits 5, 4, 1, and 0—Reserved: These bits are reserved; they are always read as 1 and cannot be
modified.
Bits 3 and 2—Clock Select 1 and 0 (CKS1, CKS0): These bits select the A/D conversion time.
The conversion time should be changed only when ADST = 0.
Set bits CKS1 and CKS0 to give a conversion time of at least 10 µs.
