nally, calibration should be initiated through the appli-
cation of LRST_N, in which case the calibration takes
place upon release of the LRST_N. Some applications
may require initiating calibration by asynchronously
writing a one- to two-wire serial interface to register
12, in which case the calibration is delayed until the
beginning of the next frame. Calibration will continue
to occur every frame until a zero is written to register

interrupted during the calibration process to prevent
output noise from corrupting the calibration. After the
calibration process is complete, ROW_VALID goes
