Hi All

I need a little bit of help and information. I want to send 8 bits of data on a 4 bit bus to a memory mapped device. Is this how you do it?

First the high nibble is sent, using the following

XBYTE[0x0a000] = 0x28 | 0x0f0;

delay(micro-seconds)

Then the low nibble.

XBYTE[0x0a000] = 0x28 | 0x0f;

Is this correct or not?

Thanx in advance
