15.4.3.7.1 Leading-Edge Blanking Counter Period Calculation
The LEB counter value is stored in the PGxLEB[19:4] bits and defines the period of the
counter (TLEB). The lower four bits are read-only and always read as
‘0’, yielding a minimum LEB resolution of 16 PGx_clks. The minimum
blanking period is five PGx_clks, which occurs when LEB[15:0] ≤ 4.
