Okay,
. . . MOV R1, #LOW(PortC_Out) ; Page reg set at 7F MAIN: (2) MOV A, #00010000b ; Set PortC[4] (2) MOVX @R1, A (1) CLR A (2) MOVX @R1, A (3) JMP MAIN = 10 instruction cycles 10 instructions cycles X 4 clock cycles/instruction cycle = 40 clocks; but the AN2131 runs at double the clock speed internally. Thank you for your help! Steve |
