MSHUT High Precision Operation
The MSHUTPOS_HP register allows fine precision 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 53. By using the MSHUTPOS_HP register,
the rising and falling edges of MSHUT can be delayed by
multiples of the OL counter length that has been set in the
OLEN register. For example, if MSHUTPOS_HP = 3, the

MSHUT rising and falling edges are delayed by three OL
counter cycles after the falling edge of HD, as shown in
Figure 56.
Figure 56 provides an example of high precision MSHUT and
SUBCK timing. In this example, the length of the OL counter is
shorter. This provides finer precision control of the placement
of the MSHUT pulse within a line.
