2.7 Effects of SLEEP Mode on the

On-chip Oscillator

When the device executes a SLEEP instruction, the on-

chip clocks and oscillator are turned off and the device

is held at the beginning of an instruction cycle (Q1

state). With the oscillator off, the OSC1 and OSC2 sig-

nals will stop oscillating. Since all the transistor switch-

ing currents have been removed, SLEEP mode

achieves the lowest current consumption of the device

(only leakage currents). Enabling any on-chip feature

that will operate during SLEEP will increase the current

consumed during SLEEP. The user can wake from

SLEEP through external RESET, Watchdog Timer

Reset or through an interrupt.
