How to MCLR by code for 16F877

[Dave]

Firat, Yes it is possible to effect an MCLR function from within your code. Paste these lines into your code where you want to effect the reset function. I use this code on an 16F876 and it works great. I use it after waking from sleep mode.

Asm
bcf PCLATH, 3
bcf PCLATH, 4
goto 0
EndAsm

Try it and let me know....

I am grateful to you and all moderators and members to have shared the vast knowledge by this remarkably useful and accurate forum. Thanks for all you do.

The software reset is not a complete hardware reset. Keep that in mind, since some registers are not really reset as in a power cycle.
