Hello Mr. Jeff Corr,

For example, If I wanted to send 11110000
out on port 1.0, and 1.1 was used as a serial clock, I *could* :

 
Example:
	MOV	A, #0xF0
        MOV     R1,#0x08     ;Send 8 bits
putc1:  RRC     A            ;Move next bit into carry
        MOV     P1.0,C       ;Write next bit
	SETB	P1.1         ;STROBE SERIAL CLOCK
	CLRB	P1.1	     ;""      ""
        DJNZ    R0,*         ;For DATA bit
	RET

Good luck,
