8.8
In alternate, power-managed Run modes, the external
bus continues to operate normally. If a clock source
with a lower speed is selected, bus operations will run
at that speed. In these cases, excessive access times
for the external memory may result if Wait states have
been enabled and added to external memory opera-
tions. If operations in a lower power Run mode are
anticipated, users should provide in their applications
for adjusting memory access times at the lower clock
speeds.

In Sleep and Idle modes, the microcontroller core does
not need to access data; bus operations are
suspended. The state of the external bus is frozen, with
the address/data pins and most of the control pins hold-
ing at the same state they were in when the mode was
invoked. The only potential changes are to the CE, LB
and UB pins, which are held at logic high.
