Description
Standby Timer Select 0 to 2
These bits select the MCU wait time for clock
stabilization when software standby mode is
cancelled by an external interrupt. With a crystal
oscillator (table 20.3), select a wait time of 8ms
(oscillation stabilization time) or more, depending on
the operating frequency. With an external clock,
select a wait time of 2 ms or more.
