Stop Modes:
The stop instruction places the MPU in low power consumption mode. The stop instruction
disables clocking of most internal registers. Timer control register bits 6 and 7 (TCR6 and
TCR7) are altered to remove any pending timer interrupt requests and to disable any further
timer interrupts. The DS and AS output lines go “l(fā)ow” and the RW_n line goes “high”. The
multiplexed address/data bus goes to the data input state. The high order address lines
remain at the address of the next instruction. External interrupts are enabled by clearing the
I bit in the condition code register. All other registers, memory, and I/O remain unaltered.
Only an external interrupt or reset will bring the MPU out of the stop mode. Figure 11
shows a flowchart of the stop function.
