5.14 Stop Mode Operation
In stop mode, all operations of the
μ
C cease. The
μ
C enters stop mode when the STOP instruction is
executed and exits stop mode when an external trigger is activated (by a falling signal on the RC or RD
port). When the designated signal is accepted, the
μ
C awakens and executes the next instruction. In the
