General call address
A General Call (GC) occurs when a Master-Transmitter initiates a transfer containing a
Slave address of 0000000b, and the R/W bit is logic 0. All Slave devices capable of
responding to this broadcast message will acknowledge the GC simultaneously and then
behave as a Slave-Receiver. The next byte transmitted by the Master will be accepted and
acknowledged by all Slaves capable of handling the special data bytes. A Slave that cannot
handle one of these data bytes must ignore it by not acknowledging it. The I
lists the possible meanings of the special bytes that follow the first GC address byte, and the
actions to be taken by the Slave device(s) upon receiving them. A common use of the GC by
a Master is to dynamically assign device addresses to Slave devices on the bus capable of a
programmable device address.
The UPSD34xx can generate a GC as a Master-Transmitter, and it can receive a GC as a
Slave. When receiving a GC address (00h), an interrupt will be generated so firmware may
respond to the special GC data bytes if desired.
Serial I/O engine (SIOE)
At the heart of the I
automatically handles low-level I
clock generation and synchronization) and it is controlled and monitored by five SFRs.
