Jul 15, 2010
Notes 1. When AMPH = 1
The STOP mode can be released by the following two sources.
(a) Release by unmasked interrupt request
High-speed system
clock (X1 oscillation)
is selected as CPU
clock when STOP
instruction is executed
High-speed system
clock (external clock
input) is selected as
CPU clock when STOP
instruction is executed
Internal high-speed
oscillation clock is
selected as CPU clock
when STOP instruction
is executed
When an unmasked interrupt request is generated, the STOP mode is released. After the oscillation stabilization
time has elapsed, if interrupt acknowledgment is enabled, vectored interrupt servicing is carried out. If interrupt
acknowledgment is disabled, the next address instruction is executed.
