LTC2942
APPLICATIONS INFORMATION
Read Protocol
The master begins a read operation with a START condition
followed by the seven bit slave address 1100100 and the
R/ W bit set to zero, as shown in Figure 6. The LTC2942
acknowledges and then the master sends a command
byte which indicates which internal register the master is
to read. The LTC2942 acknowledges and then latches the
command byte into its internal register address pointer. The
master then sends a repeated START condition followed
by the same seven bit address with the R/ W bit now set
to one. The LTC2942 acknowledges and sends the con-
tents of the requested register. The transmission is ended
when the master sends a STOP condition. If the master
acknowledges the transmitted data byte, the LTC2942
increments its address pointer and sends the contents of
the following register as depicted in Figure 7.
Alert Response Protocol
In a system where several slaves share a common inter-
rupt line, the master can use the alert response address
(ARA) to determine which device initiated the interrupt
(Figure 8).
