7.8 Operation in Power-Managed
Modes
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 operations. If
operations in a lower power Run mode are anticipated,
user applications should provide memory access time
adjustments 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
holding at the same state they were in when the mode
was invoked. The only potential changes are the CE,
LB and UB pins, which are held at logic high.
