Functional description

WRITE mode
In this mode the master transmitter transmits to the STCN75 slave receiver. Bus protocol is
shown in
Figure 11
. Following the START condition and slave address, a logic '0' (R/W = 0)
is placed on the bus and indicates to the addressed device that word address will follow and
is to be written to the on-chip address pointer.
These modes are shown in the WRITE mode typical timing diagrams (see
Figure 11
, and
Figure 12
, and
Figure 13 on page 24
).
Figure 11.
Typical pointer set followed by an immediate READ from the
configuration register
