17.4
The Power-down mode is entered by executing a
SLEEP instruction. This clears the Watchdog Timer and
postscaler (if enabled). The PD bit is cleared and the
TO bit is set (in the CPUSTA register). In SLEEP mode,
the oscillator driver is turned off. The I/O ports maintain
their status (driving high,low, or hi-impedance input).

The device can wake-up from SLEEP through one of
the following events:
• Power-on Reset
• Brown-out Reset
• External RESET input on MCLR/V
• WDT Reset (if WDT was enabled)
• Interrupt from RA0/INT pin, RB port change,
The following peripheral interrupts can wake the device
from SLEEP:
• Capture interrupts
• USART synchronous slave transmit interrupts
• USART synchronous slave receive interrupts
• A/D conversion complete
• SPI slave transmit/receive complete
• I
Other peripherals cannot generate interrupts since dur-
ing SLEEP, no on-chip Q clocks are present.

Q2
Any RESET event will cause a device RESET. Any
interrupt event is considered a continuation of program
execution. The TO and PD bits in the CPUSTA register
can be used to determine the cause of a device
RESET. The PD bit, which is set on power-up, is
cleared when SLEEP is invoked. The TO bit is cleared
if WDT time-out occurred (and caused a RESET).
When the SLEEP instruction is being executed, the next
instruction (PC + 1) is pre-fetched. For the device to
wake-up through an interrupt event, the corresponding
interrupt enable bit must be set (enabled). Wake-up is
regardless of the state of the GLINTD bit. If the GLINTD
bit is set (disabled), the device continues execution at
the instruction after the SLEEP instruction. If the
GLINTD bit is clear (enabled), the device executes the
instruction after the SLEEP instruction and then
branches to the interrupt vector address. In cases
where the execution of the instruction following SLEEP
is not desirable, the user should have a NOP after the
SLEEP instruction.
The WDT is cleared when the device wakes from
SLEEP, regardless of the source of wake-up.
17.4.1.1
When the oscillator type is configured in XT or LF
mode, the Oscillator Start-up Timer (OST) is activated
on wake-up. The OST will keep the device in RESET
for 1024T
when considering the interrupt response time when
coming out of SLEEP.

If the global interrupt is disabled (GLINTD
is set), but any interrupt source has both its
interrupt enable bit and the corresponding
interrupt flag bit set, the device will imme-
diately wake-up from SLEEP. The TO bit is
set and the PD bit is cleared.
