PIC18F47J53 CCS C Compiler 5.090 Sleep vs Deep Sleep

[Marco27293]

Now, it seems working :grin:

How can I keep PIN_B2 as output high during sleep?

before I go to sleep I set:

output_high(PIN_B2);

at wake up:

LATB = 0b00000100;
PORTB = 0b00000100;
set_tris_b(0b11111011);

BUT during sleep it goes low... When PIC wake-up enter in a isr which performs a reset_cpu(); command

How is the pin used?. Is USB enabled on the device?. If so it is the USB D-
pin and this overrides normal I/O. Or if any #PIN_SELECT makes use of
the pin this too will override the normal I/O. Possibly if the mapped
peripheral is turned off then the pin goes low. #PIN_SELECT overrides
the normal I/O behaviour.

If the pin is setup as a normal I/O pin, then it'ld stay high if set high.

However I'd suspect the most likely thing is that ROSSLP is on. This
means the system 'reference clock' will be output on this pin when the
chip is asleep. However this oscillator will stop in your sleep mode, so it'd
output a static level.
So try:

Thank you Ttelmah,

Last question, now I'm controlling wdt via software in this way:

[Ttelmah]

No, it is only the enable bit that overrides software control.
Setting the division in the fuses is actually being done for you.
The prescaler is only settable by the fuses. When you add the line:

setup_wdt(WDT_4S);

The compiler automatically sets the fuses to give the 4 second nominal
timing. If you look at the .lst file with this set, you will find /1024 is
set.

This is why you can't actually 'change' the timing. Once it is set, it is
fixed in the fuses.
