I put a 10K to ground and loaded the program and tried again. Still no luck getting the MCU to work. For my first attempt I am simply trying to see p1.1 toggle on and off plus see the sysclk on p3.7.
here is the code I have written, Is there some PSR I need to set to get the MCU to work?
FORG: ORG 0000H
JMP START
START:
MOV 0C2H,#00H ;SET PORTS AS QUASI BIDIRECTIONAL
MOV 0C3H,#00H
MOV 0C6H,#00H
MOV 0C7H,#00H
TIMER_TEST:
CALL LEDON ;P1.1 SHOWS PULSES
CALL POINT_1_MS
CALL LEDOFF
CALL POINT_1_MS
JMP TIMER_TEST

POINT_1_MS:
MOV R3,#01H
