Dear TI Team:
I'm trying to use the internal test pattern generator to test the connection between DS90UB921 and DS90UB928(as follow).
The Display only supports 44MHz, 1152x576@60fps.
I try to test pattern from ds90ub921, but it can't display.
1. My test code is follow. Is it any wrong? or can I test pattern from ds90ub928?

2. Refer to Exploring the Int Test Pattern Generation Feature of FPD[1]Link III IVI Devices.pdf, Table 3-9. Pattern Generator Clock Divider N Configuration (PGCDC1),
clock = 200Mhz / N
How to set 44Mhz ?
Thanks.
