Wake-up from SLEEP
SLEEP (Power-Down) Mode
Sleep (Power-down) mode is a mode where the device is placed in it’s lowest current consump-
tion state. The device oscillator is turned off, so no system clocks are occurring in the device.
Sleep mode is entered by executing a
If enabled, the Watchdog Timer will be cleared but keeps running, the PD bit in the STATUS reg-
ister is cleared, the TO bit is set, and the oscillator driver is turned off. The I/O ports maintain the
status they had, before the
For lowest current consumption in this mode, all I/O pins should be either at V
external circuitry drawing current from the I/O pin and the modules that are specified to have a
delta sleep current should be disabled. I/O pins that are hi-impedance inputs should be pulled
high or low externally to avoid switching currents caused by floating inputs. The T0CKI input
should also be at V
pull-ups on PORTB should be considered.
The MCLR pin must be at a logic high level (V
Some features of the device that consume a delta sleep current are enabled / disabled by device
configuration bits. These include the Watchdog Timer (WDT) and Brown-out Reset (BOR) cir-
cuitry modules.
The device can wake-up from SLEEP through one of the following events:
1.
2.
3.
The first event will reset the device upon wake-up. However the latter two events will wake the
device and then resume program execution. The TO and PD bits in the STATUS register can be
used to determine the cause of device reset. The PD bit, which is set on power-up is cleared
when SLEEP is invoked. The TO bit is cleared if WDT wake-up occurred.
When the
