(4) Access to Indirect Registers
To set the user-specified gamma table, use indirect access registers.
For indirect access, seven bytes of direct registers are used. These direct registers are as follows:
Target Address 0-7 Register (Direct address: 0xB0)
Target Address 8-15 Register (Direct address: 0xB1)
Target Address 16-23 Register (Direct address: 0xB2)
Target Address 24-31 Register (Direct address: 0xB3)
Target Address 32-39 Register (Direct address: 0xB4
* This register is not used in this camera.)
Data Register (Direct address: 0xB5)
Data Length Register (Direct address: 0xB6)
Sum Register (Direct address: 0xB7)
The function of each register is as follows.
Target Address *-* Register
Indicates the address whose data is referred to or to which data is written.
Data Register
During read operation, data stored in the Target Address *-* register is read.
During write operation, the specified data is written to the Target Address *-* Register.
When read or write operation is completed, the Target Address *-* Register is
incremented.
Data Length Register
Set the number of bytes to be read continuously. (Specified value +1) bytes of data are
read continuously.
If 0 is specified, one byte of data is read.
Sum Register
Every time a write or read command is executed for the Data Register, one-byte
hexadecimal data read or written is added to the value of this register and the result is
stored in this register.
When continuous write or continuous read is performed after 0x00 is written into this
register, the camera side Check Sum of the data read or written data is stored after the
continuous write or continuous read.
