ADCR is an 8-bit readable/writable register that enables or disables external triggering of A/D
conversion operations.
ADCR is initialized to H'3F by a reset, and in standby mode or module stop mode.
Bits 7 and 6—Timer Trigger Select 1 and 0 (TRGS1, TRGS0): These bits 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).
