'RTCC and SLEEP'

Possible newbie question.

Does the PIC16CXX RTCC (f1) continue to increment from the internal
instruction cycle clock during a SLEEP instruction?
According to the simulator it does, but the data sheet indicates
otherwise.
Thanks.

No, the oscillator stops.  Sounds like a bug in the simulator.

Note that on the 16C64 and 16C74, you can hook up a crystal to timer 1 if
you need an accurate timer during sleep.

The SLEEP instruction works by disabling the CLK oscillator so the
RTCC has'nt got anything to count.
The simulator does not replicate this action. :)
