I checked the status with

   BTFSS   STATUS, NOT_PD
   GOTO    Start

In PowerOn: i make my initializing, i make my work between  Start: and the
SLEEP. When the WDT times out, the PIC is reseted and start at address 0.

The code works fine with 16C84.

Isn4t this right?

                CBLOCK 0x07
