QADC64E Enhanced Mode Operation
14.3.1
The QADCMCR contains fields and bits that control freeze and stop modes, operating mode of the
QADC64E module, determine the privilege level required to access most registers and master/slave
operation.
14.3.1.1
When the STOP bit in the QADCMCR is set, the QADC64E clock (QCLK) which clocks the A/D
converter, is disabled and the analog circuitry is powered down. This results in a static, low power
consumption, idle condition. The stop mode aborts any conversion sequence in progress. Because the bias
currents to the analog circuits are turned off in stop mode, the QADC64E requires some recovery time (T
in Appendix F: Electricl Characteristics) to stabilize the analog circuits after the stop enable bit is cleared.
