12.6. Sync Signal Output Setting Method
The tables below describe the parameters related to output switching for the sync signal output pins S0
(CXD3172AR 44pin), S1 (CXD3172AR 46pin), S2 (CXD3172AR 47pin), S3 (CXD3172AR 48pin), S4
(CXD3172AR 49pin).
Since a setup of S0-S4 pins are controlled by SG MODE, the setting method is as follows.
1. Set SSELOFF (CAT12 Byte12 bit5) to ”1”. (S pins control by SG MODE is off)
2. Set up the parameters of each S* pins. (CAT1 Bite7-8)
3. Write CAT1 into EEPROM.
4. Set SSELOFF to ”0” back.
