Functional description
Data Write Register (DW)
The data write register contains the byte to transfer to a camera register. DW can be written only
when SR bit RDY is set.
Table 11: Data write register
Data Read Register (DR)
The Data Read Register contains the byte transferred from a camera register. DR is valid only
when SR bit RDY is set.
Table 12: Data Read register
Indirect registers
The microprocessor interface indirect registers are accessed by the host using an indirect address
base of 0x8FF0 / 0xCFF0 (write / read). Register offsets are listed in
