H
ORIZONTAL MODE DETECTION
This function block determines the following 4 parameters: Hper, Hpol, Hpres and Hcha. The functional block diagram is
shown in Fig.29.
The 12-bit counter for the determination of the horizontal period has a synchronous reset and will be reset by the
prescaled and differentiated horizontal pulse HSYNC_P, coming from the horizontal prescaler, or in case the counter
reaches the value FF0H as defined by the comparator. The latter situation will occur if no sync pulses are coming in or
if the frequency of the incoming sync pulses is too low.
The 12-bit register, that will store the 4 line time period, is only enabled if the signal HENA is HIGH.
19.2.5.1
Parameter Hper
Based on this configuration, the resulting accuracy for Hper will be:
