Figure 1-13 Serial Interface Bus (SIB) Message Transmission Timing Diagram
*1
*2
The SDAT goes low due to SCSR0 (write pending) set in all devices that are requesting the bus.
The previous master sets SCSR2 (previous master) and sets CHOUT high, all others clear SCSR2. The
next device with CHIN high and SCSR0 set becomes bus master, and clears CHOUT to low.
The bus master interrupts its MPU and the MPU loads the shift register. Writing to SR0 clears SCSR0
(write pending) and sends the message. The SIB waits until the shift register SR0 is written. Any device
that has SCSR4 set (read pending), sets SCSR5 (deaf) indicating the MPU never read the last message
sent to it. Reading SR3 clears SCSR4 (read pending).
The 32-bit message is sent by the bus master during states 3-34. The BEGIN low time begins on the
transfer of data to the masters shift register during state 2 and stays low until the first transmit data bit
time in state 3. The output data is transferred on the rising edge of SCLK with the input data latched on
the falling edge of SCLK.
The bus master sets SDAT to '1' signaling the end of transmission.
The receiver device pulls SDAT low signaling the bus master that the message was received. If the
receiving device does not pull SDAT low then the bus master sets SCSR3 (message not acknowledged)
indicating the message was not received, and will interrupt its MPU in the next state (State 37).
The receiver sets SCSR4 (read pending) and interrupts its MPU. The bus master (sending device) outputs
a high level on SDAT and interrupts its MPU if SCSR3 (message not acknowledged) was set in state 36,
signaling the message was not received.
Wait in state 0 for message processing and next message transmission bus request.
