MSHUT High Precision Operation
The MSHUTPOS_HP register allows more precise control of
the MSHUT position within a line. Under normal MSHUT
operation when MSHUTPOS_HP = 0, the MSHUT polarity
changes from high to low on the negative edge of the HD pulse,
as shown in Figure 44. By using the MSHUTPOS_HP register,
the rising and falling edges of MSHUT can be delayed by mul-
tiples of the OL counter length, which has been set in the OLEN
REV. 0

register. For example, if MSHUTPOS_HP = 3, the MSHUT
rising and falling edges will be delayed by three OL counter
cycles after the falling edge of HD, as shown in Figure 46.
Figure 46 provides an example of high precision MSHUT and
SUBCK timing. In this example, the length of the OL counter
is shorter. This provides very precise control of the placement
of the MSHUT pulse within a line.
