CHAPTER 7 REAL-TIME OUTPUT FUNCTION
<Examples of setting data in port 0 buffer registers>
• 4-bit × 2-channel operation
MOV P0L, #05H ; Sets 0101B in P0L
MOV P0H, #0C0H ; Sets 1100B in P0H
• 8-bit × 1-channel operation
MOV P0L, #0C5H
or
MOV P0H, #0C5H
; Sets 0101B in P0L and 1100B in P0H
The timing for transfer to the output latch can be determined by the following three sources:
• Interrupt from timer/event counter 1 (INTC10 or INTC11)
• INTP0 external interrupt
