5.5 Low Power Operation
5-16
Both STOP and WAIT suspend CPU operation until a reset or interrupt occurs. The
WAIT condition suspends processing and reduces power consumption to an interme-
diate level. The STOP condition turns off all on-chip clocks and reduces power con-
sumption to an absolute minimum while retaining the contents of all 1024 bytes of
RAM.
