Message Format for Writing the MAX5945
A write to the MAX5945 comprises of the MAX5945’s
slave address transmission with the R/W bit set to 0, fol-
lowed by at least one byte of information. The first byte
of information is the command byte (Figure 11). The
command byte determines which register of the
MAX5945 is written to by the next byte, if received. If
the MAX5945 detects a STOP condition after receiving
the command byte, then the MAX5945 takes no further
action beyond storing the command byte. Any bytes
received after the command byte are data bytes. The
first data byte goes into the internal register of the
MAX5945 selected by the command byte. If the
MAX5945 transmits multiple data bytes before the
MAX5945 detects a STOP condition, these bytes store
in subsequent MAX5945 internal registers because the
control byte address auto-increments.
Any bytes received after the control byte are data
bytes. The first data byte goes into the internal register
of the MAX5945 selected by the control byte (Figure 8).
If multiple data bytes are transmitted before a STOP
condition is detected, these bytes are stored in subse-
quent MAX5945 internal registers because the control
byte address auto-increments.
