It is not necessary for the write and read mode transfers
to occur immediately in sequence. I
other devices do not impact the MAX5816 readback mode.
Toggling between readback modes is based on the length
of the preceding write mode transfer. Combined format I
readback operation is resumed if a write command greater
than two bytes but less than four bytes is supplied. For
commands written using multiple register write sequences,
only the last command executed is read back. For each
command written, the readback sequence can only be
completed one time; partial and/or multiple attempts to
readback executed in succession will not yield usable data.
The MAX5816 is fully compatible with existing I
tems. SCL and SDA are high-impedance inputs; SDA has
an open drain which pulls the data line low to transmit
data or ACK pulses.
