I'm having trouble ICSP programming my 16LF627's. The 16F627's program fine. My circuit has a 10K pullup on MLCR, and RB6 and RB7 are not attached to anything. There is less than a 10mA load on Vcc. Here's my processor configuration: __CONFIG _PWRTE_ON & _WDT_OFF & _LVP_OFF & _INTRC_OSC_NOCLKOUT & _MCLRE_ON & _CP_OFF & _BODEN_ON My Promate II is using the ICSP module as I said the same circuit w/ the 16F627 programs fine. Promate II settings: device = 16F627 (there's no LF option) vdd min = 3.0V Vdd max = 5.5V Vpp = 13.0V no sqtp low voltage program not enabled Any suggestions?
