Table 5-6 lists the FPGA memory map for the 8-bit chip select. Addresses are given as word
addresses as required by the MV64460.
5.2.1 Main Registers
The main registers provide revision information for the FPGA firmware, as well as status and
control for various functions. Table 5-7 lists the main registers.
FPGA Revision Register
The FPGA Revision Register contains the binary-coded decimal revision number for the current
FPGA firmware. It is formatted as version number (most significant 16-bits) and revision number
(least significant 16-bits).
NOTE:
The revision number is subject to change.
