3.4.1.2 Write Parameters

Figure 3-61 describes the command parameters.

Figure 3-61 Write Parameters

MSB	Byte 1						LSB
b7	b6	b5	b4	b3	b2	b1	b0

b(7:3)	Reserved
b(2)	Manual Mode – Parallel Interface HSYNC Polarity: 0: Falling Edge Active (Negative Pulse) 1: Rising Edge Active (Positive Pulse)
b(1)	Manual Mode – Parallel Interface VSYNC Polarity: 0: Falling Edge Active (Negative Pulse) 1: Rising Edge Active (Positive Pulse)
b(0)	Parallel Interface Sync Polarity Mode: 0: Automatic Mode 1: Manual Mode

This command may be needed when using the parallel interface port. This command is not applicable for BT656 sources. In Automatic mode, the system can typically determine the appropriate polarity of the syncs. In Manual mode, the user is allowed to specify these polarities.
