Frame Marker Control (R090h)
FMI[2:0]: Sets FMARK output interval by FMI register setting according to the update period of display
data and transfer rate. Set FMKM = 1 if FMARK signal is output from FMARK pin. See “FMARK
Interface” for detail.

FMP[8:0]: Sets the output position of frame synchronous signal (frame marker). A pulse (FMARK) is
output by starting from back porch during a 1H period when FMP[8:0] = 9’h000 (high active, amplitude:
IOVCC1-GND). FMP[8:0] is used as a trigger signal for write operation in synchronization with frame.
Setting range: 9’h000 ≤ FMP ≤ BP + NL + FP
For details, see “FMARK Interface”.
