Is there a way to reset the chip with software? Do I just write: goto 0x000 regards -- http://www.piclist.com#nomail Going offline? Don't AutoReply us! email spam_OUTlistservTakeThisOuTmitvma.mit.edu with SET PICList DIGEST in the body

Well, it says "Reset all registers and flags that are affected by a MCLR Reset". Note that the PCH/PCL are all set to zero on a MCLR reset... Jan-Erik. {Original Message removed}

See also the "SIMPLIFIED BLOCK DIAGRAM OF ON-CHIP RESET CIRCUIT" on page 24 of DS39564B. Note "RESET Instruction" in the picture. RESET does *exactly* the same thing as an external MCLR reset or a "VDD Rise Detect" reset, as far as I can see... Jan-Erik. {Original Message removed}

However, if your initialization code sets all the state it cares about, then it can be like a reset. ***************************************************************** Embed Inc, embedded system specialists in Littleton Massachusetts (978) 742-9014, http://www.embedinc.com -- http://www.piclist.com#nomail Going offline?

(Note that the subject specifies a series 18 chip...) RESET Jan-Erik. PS. And, as has been vented earlier on the list, it sometimes pay to check the earlier replys in the thread... DS.
