Post by thread:[PIC]: I/O during programing

Most programmable devices tristate during programming but I do not see an exact reference to this other than on reset, the TRIS registers are all set to 1, so tristated. Anyone know this for sure? _________________________________________________________________ Express yourself instantly with MSN Messenger!

Anyone know this for sure? The programming specs usually say that all pins except those used for programming go to high impedence once programming mode is entered. ***************************************************************** Embed Inc, embedded system specialists in Littleton Massachusetts (978) 742-9014, http://www.embedinc.com -- http://www.piclist.com hint: PICList Posts must start with ONE topic: [PIC]:,[SX]:,[AVR]: ->uP ONLY!
