BIT FIELD
Enable Xenon flash. Same physical register as Reg0x023, bit 13.
0: Use READ mode, context A, Reg0x021.
1: Use READ mode, context B, Reg0x020.
Note that bits found only in the READ mode context B register is
always taken from that register.
Enable LED flash. Same physical register as Reg0x023, bit 8.
0: Use vertical blanking, context A, Reg0x008.
1: Use vertical blanking, context B, Reg0x006.
0: Use horizontal blanking, context A, Reg0x007.
1: Use horizontal blanking, context B, Reg0x005.
Page mapping register. Must be kept at 0 to be able to WRITE
to/READ from sensor. Used in the S OC to access other pages with
registers.
Special address to perform 8-bit (instead of 16-bit) READs and
WRITEs to the sensor. For additional information, see “Two-
Wire Serial Interface Sample” on page 54 and “Appendix A” on
page 52.
Hardwired READ only.
