TS-4400 FPGA REGS
From embeddedTS Manuals
The FPGA's base address is returned from inquiry to the system BIOS. Once the BIOS has assigned a base address for the FPGA on the PCI bus, this table of registers will appear at the listed offset. TBD: Insert table of register functions and their address offsets.
fpga_reg_200h <= 8'h44 -- TBD Function
fpga_reg_16fh <= 8'd0 -- TBD Function
fpga_reg_202h <= 8'd0 -- TBD Function, probably RTC-related
fpga_reg_204h <= 8'd0 -- i2c, rtc mirror enable - need bitwise definition.
fpga_reg_205h <= 8'd0 -- red/grn LEDs
fpga_reg_206h <= 8'd0 -- spi flash select, lan LED, power cycle
flash select pad 1 is at 0x206 bits 2 and 3 (out enable and out value).
flash select pad 2 is at 0x206 bits 5 and 6 (out enable and out value).
power_cycle_pad_o is at 0x206 bit 7
fpga_reg_207h <= 8'd2 -- jtag ?
fpga_reg_20ah <= 8'd0 -- SPI to FPGA flash
