(1) This register contains the user
image buffer write settings. Writing this register primes the user image buffer
write state machine to begin monitoring the USB / GPIF FIFO for an image
transfer to the user image buffer. The first row received over USB / GPIF is
written to buf_wstart_row of the user image buffer. The buffer write state
machine accepts buf_wstart_numrows of data, after which the buffer stops writing
data until a new write to this register is performed. In addition, writing to
this register resets the USB / GPIF FIFO.
(2) Valid values for buf_wstart_row
are 0 through (TOTAL_ROWS_ON_DMD – 1). Buf_wstart_row must be less than or equal
to TOTAL_ROWS_ON_DMD – buf_wstart_numrows.
(3) Buf_wstart_numrows valid values
are 1 thru TOTAL_ROWS_ON_DMD.
