General Release Specification — MC68HC05RC16
Section 6. Low-Power Modes
6.1 Contents
6.2 Introduction
This section describes the low-power modes.
6.3 Stop Mode
The STOP instruction places the MCU in its lowest power-consumption
mode. In stop mode, the internal oscillator is turned off, halting all
internal processing, including timer operation.
During stop mode, the CTCSR ($08) bits are altered to remove any
pending timer interrupt request and to disable any further timer
interrupts. The timer prescaler is cleared. The I bit in the CCR is cleared
to enable external interrupts. All other registers and memory remain
unaltered. All input/output lines remain unchanged.
NOTE:
The EIMSK bit is not cleared automatically by the execution of a STOP
instruction. Care should be taken to clear this bit before entering stop
mode.
