Post by thread: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. ///////////////////////////////////////////////////// Jamie Lawson \ spam_OUTjlawsonTakeThisOuTevbhort.uoguelph.ca \ University of Guelph \ Voice (519) 824-4120 x2616 \ Guelph, Ontario \ FAX (519) 767-0755 \ Canada \ \ \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\

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. Eric

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. :) -- Cheers Tom
