2.4.3 Sync Signal Generation Adjustment Settings (for demonstration)
OKI Semiconductor
* The registers in this section are published as settings for generating the necessary sync signals for
monitor display in evaluation boards. Because only standard signals are assumed, the operation of final
products is not guaranteed. Use these settings only when using an evaluation board.
ISYNC Initial value: 0; Setting range: 0 to 1
HSSEL Initial value: 0; Setting range: 0 to 1
SHSDL[7:0] Initial value: 0011_1111; Setting range: 0000_0001 to 1111_1111
