Seiko Epson Corporation
S5U13706P00C100 Evaluation Board
Rev. 1.2
The S1D13706 has 8 configuration inputs (CNF[7:0]) which are read on the rising edge of
RESET#. All S1D13706 configuration inputs are fully configurable using a ten position
DIP switch as described below.
Note
1
To enable the Hardware Video Invert function the following are required:
• GPIO pins must be enabled (S1-4 closed).
• GPIO0 must be connected to S1-9 (Jumper JP1 set to 1-2).
• GPIO Pin Input Enable (REG[A9h] bit 7) must be set to 1b.
• GPIO0 Pin IO Configuration (REG[A8h] bit 0) must be set to 0b.
• Hardware Video Invert Enable bit (REG[70h] bit 5) must be set to 1b.
