6.3.1.2
SPI Register Decoding
All SPI accesses from the IPMC towards the FPGA with the SPI select signal IPMC_SPI_SS_FPGA_
asserted are accepted.
6.3.2
POST Code Register
The FPGA provides an 8-bit wide register to store POST codes to the LPC I/O address 0x80. The
two nibbles of the register are converted to 7-segment codes and are displayed as two hex
values by two 7-segment LED Displays.
The IPMC may read the POST code using the SPI interface (with the signal IPMC_SPI_SS_FPGA_
asserted) and the SPI address 0x7F.
