Table 12: 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 MX805A MXB (bit 7) first, LSB (bit 0) last.

2. Data is clocked into the MX805A and into the microcontroller 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 microcontroller serial interface formats, the MX806A will work with either polarity

Serial Clock pulses.
