Registers and address mapping
In addition to being written and read for data transfers, the microcontroller interface
includes some registers that can be accessed or written by the microcontroller:
Register/command
Address
(Hex)
Settings write
000-003
Write data
004-007
Read data
008-00B
Destination register (read)
00C-00F
Destination register (write)
010-013
Status register (read)
014-017
Firmware revision number
018-01B
RAM (read/write)
800-FFF
Table 17 : Register addresses
When ordered to read a register the interface inside the FPGA will then be given the
bus and will shift out the required register to the microcontroller.
