BSD COMMUNICATION FRAME
To transfer data between a master and slave, or vice versa, the
construction of a BSD frame is required. A BSD frame contains
seven key components: pause/sync, a direction (DIR) bit, the
slave address, the register address, data, parity bits (P1 and P2),
and the acknowledge bit from the slave.
If the master is transmitting data, all bits except the acknowledge
bit are transmitted by the master.
If the master is requesting data from the slave, the master transmits
the pause/sync, direction bit, slave address, register address, and
P1. The slave then transmits the data bytes, the P2 bit, and the
acknowledge bit in the following sequence:
1.
Pause: ≥ three synchronization pulses
2.
DIR: signifies the direction of data transfer
DIR = 0 if master sends request
DIR = 1 if slave sends request
3.
Slave address
4.
Register address: defines register to be read or written
5.
Bit 3 is set to write and cleared to read
6.
Data: 8-bit read only receive register
7.
P1 and P2
P1 = 0 if even number of 1s in eight previous bits
P1 = 1 if odd number of 1s in eight previous bits
P2 = 0 if even number of 1s in data-word
P2 = 1 if odd number of 1s in data-word
8.
Acknowledge bit
ACK = 0 if transmission is successful
The acknowledge bit is always transmitted by the slave to
indicate whether the information was received or transmitted.

BSD Example Pulse Widths
An example of the different pulse widths is shown in Figure 54.
For each bit, the period for which the bus is held low defines
what type of bit it is. If the bit is a sync bit, the pulse is held low
for one bit. If the bit is 0, the pulse is held low for three bits. If
the bit is 1, the pulse is held low for six bits.
If the master is transmitting data, the signal is held low for the
duration of the signal by the master. An example of a master
transmitting a 0 is shown in Figure 55. If the slave is
transmitting data, the master pulls the bus low to begin
communication. The slave must pull the bus low before tSYNC
elapses and then hold the bus low until either t0 or t1 has elapsed,
after which time the bus is released by the slave. An example of a
slave transmitting a 0 is shown in Figure 56.

Typical BSD Program Flow
Because BSD is a PWM communication protocol controlled by
software, the user must construct the required data from each bit.
For example, in constructing the slave address, the slave node
receives the three bits and the user constructs the relevant address.
When BSD communication is initiated by the master, data is
transmitted and received by the slave node. A flowchart showing
this process is shown in Figure 57.
