Description
Standby Timer Select 3 to 0
These bits select the time the MCU waits for the
clock to stabilize when software standby mode is
cleared by an external interrupt. With crystal
oscillation, see table 26.2 and make a selection
according to the operating frequency so that the
standby time is at least the oscillation stabilization
time. With an external clock, a PLL circuit
stabilization time is necessary. See table 26.2 to
set the standby time. When DRAM is used and
self-refreshing in the software standby state is
selected, note that the DRAM’s t
RAS pulse width) specification must be satisfied.
