Hello All, i am new in the List, and i am new to the Architecture of the 12 Bit core. I have a big Problem entering the Sleepmode of the 12ce519. I am using MPLAB V412.12 and a MPLAB ICE 2000 Incircuit emulator. After entering the sleep mode, i want to wake up by watchdog timeout ( aprox 2.3 second ) or by change on pin GP3 and GP1. The wdt precscaler is tied to 1:256 and the weak pullups are on . The Config Register is 0x0e The Option Register is 0x0f If i trace with "F8" and come to the sleep command, the statusline become yello without any contens , and all of file register become 0x27 ?( the sfr to ). Change on PINS or break with "F5" doesnt have an effect. thanks ANDI
