Hi Skimask,

On Page 4-101, the typical control sequence for burst mode applications:

I have wired RSO as portb.7, WR as portb.6 and RD as portb.5.

When I send one of those sequences such as 'Write to transmit data register'
I send %00100111 where I have called RSO -b7(or bit7), WR - b6(or bit6) and RD- b5(or bit5) - portb.5 (b5) is not wired and b3-b0 (bit3 - bit0) is the data.

I hope this makes sense to you.

Thanks, Don
