Timing Information Notes
1. Command Data is transmitted to the peripheral MSB (bit 7) first, LSB (bit 0) last. Reply Data is read from the MX803A
MSB (bit 7) first, LSB (bit 0) last.
2. Data is clocked into the MX803A and into the µC on the rising Serial Clock edge.
3. Loaded data instructions are acted upon at the end of each individual, loaded byte.
4. To allow for differing µC serial interface formats, the MX803A will work with either polarity Serial Clock pulses.
