Number of microseconds to access memory if memory is in Self
Number of microseconds to access memory if memory is in Self
Refresh (0.5 us granularity).
00h = 0 us
01h = 0.5 us
02h = 1 us

3Fh = 31.5 us
NOTE: The value in this field corresponds to the memory latency
00h = 0 us
01h = 0.5 us
02h = 1 us
...
3Fh = 31.5 us
NOTE: The value in this field corresponds to the memory latency
requested to the Display Engine when Memory is in Self Refresh.
The Display LP1 latency and watermark values (GTTMMADR offset
45118h) should be programmed to match the latency in this
register.
