What am I doing wrong? this should be the simplest start...turn all port b pins on. Code: 0000 MOVLW 00 MOVWF 0A GOTO 005 NOP NOP 0005 CLRF 04 CLRF 03 MOVLW 07 MOVWF 1F 0009 BSF 03,5 CLRF 06 MOVLW FF BCF 03,5 MOVWF 06 GOTO 009 Using a 16C622, wired trivially: pin 4 1K to Vcc, .1uF to Gnd pin 5 gnd pin 14 to TTL clock module, 10MHz pin 12 to +5 looking at pins 6-13...all have about .25 v on them, but won't sink an LED (with 1K res). Help? (I don't have a scope, but im pretty sure the power is clean - 7805 with appropriate filtering off a wall wart)
