polarity
The toggle generator facilitates the synthesis of polarity signals from internal TCON signals; the
horizontal TCON_COMP and vertical TCON_PULSE signals. The selected inputs supply clock and
enable signals (resp.) for a 2-bit incrementing counter and a toggle flop that output 3 toggle and 1
polarity signals. The vlen variable sets the counter maximum, which controls the vertical sequence.
Input and vlen selection are all in the TCON_POLARITY_CTRL register.
Common types of polarity signals are given below. For synchronization of polarity and vtog_count,
a special sync mode should be entered for one frame to initialize the polarity pattern relative to the
first line of vmask.
