Serial Configuration Bus:

Bus Operation:

The controller uses the serial bus to set the characteristics of all column driver ICs by writing to all column

driver ICs in parallel. During write, the controller writes the entire data packet. The controller can also inter

rogate a single column driver IC, who's MASTER pin is pulled high. Only 1 column driver IC on a given bus

can be designated as master. During read, the controller writes the preamble, start of frame delimiter, reg

ister address, and turn around bits. It then tri-states for the bus tri-state and data bits and reads the data.

Data Packet:

The data packet consists of:

- 14 bit preamble of all 1's

- 2 bit start of frame delimiter (SFD)

- 6 bit register address - MSB first

- 1 turn around bit (TA)

- 1 bus tristate (BT)

- 8 bit data packet - MSB first

Write => write data to all column driver ICs

Read => read data from master column driver IC

Data order => Preamble first, data last; MSB first, LSB last
