SINGLE-CHIP 8-BIT MICROCONTROLLER

IDLE MODE

The user's software can invoke the Idle Mode. When the microcontroller is in this mode, power consumption is

reduced. The Special Function Registers and the onboard RAM retain their values during Idle, but the processor

stops executing instructions. Idle Mode will be exited if the chip is reset or if an enabled interrupt occurs.

POWER DOWN MODE

To save even more power, a Power Down mode can be invoked by software. If this mode, the oscillator is stopped and

the instruction that invoked Power Down is the last instruction executed. The on-chip RAM and Special Function

Registers retain their values until the Power Down mode is terminated.

On the MX10C805X either a hardware reset or an external interrupt can cause an exit from Power Down. Reset

redefines all the SFRs but does not change the on-chip RAM. An external interrupt allows both the SFRs and on-chip

RAM to retain their values.

To properly terminate Power Down, the reset or external interrupt should not be executed before VCC is restored to its

normal operating level, and must be held active long enough for the oscillator to restart and stabilize (normally less

than 10 ms).

With an external interrupt, INT0 and INT1 must be enabled and configured as level-sensitive. Holding the pin low

restarts the oscillator but bringing the pin back high completes the exit. Once the interrupt is serviced, the next

instruction to be executed after RETI will be the one following the instruction that put the device into Power Down.
