Address Registers
Register 3-5:
Address 9:8 (0x4)
Register 3-6:
Address 7:0 (0x5)
Control Register
The write only Control register performs two functions:
• Writing a value of 0x01 causes the contents of the Data registers to be written to the
FPGA bridge at the location specified by the Address registers.
• Writing a value of 0x02 causes the contents of the Data registers to be overwritten by the
contents of the FPGA bridge at the location specified by the Address registers.
Note:
Writing any other value to the Control register will be ignored.
