*When async timing mode is enabled, P_BLANK, Pin 25, becomes an active high input. P_BLANK is set to active low at Address 10h, Bit 6.
HD TIMING RESET
A timing reset is achieved by toggling the HD timing reset control
bit [Subaddress 14h, Bit 0] from 0 to 1. In this state the horizontal
and vertical counters will remain reset. When this bit is set back
to 0, the internal counters will commence counting again.

The minimum time the pin has to be held high is one clock
cycle; otherwise, this reset signal might not be recognized. This
timing reset applies to the HD timing counters only.
