CR[1:0] — COP Timer Rate Select Bits
The A/D conversion sequence begins one E-clock cycle after a write to
the A/D control/status register, ADCTL. The bits in ADCTL select the
channel and the mode of conversion.

RH
0 = The oscillator startup delay coming out of stop is bypassed and
1 = A delay of approximately 4000 E-clock cycles is imposed as the
converts to $FF (full scale), with no overflow indication. For
the MCU resumes processing within about four bus cycles.
MCU is started up from the stop power-saving mode. This
delay allows the crystal oscillator to stabilize.
