FPGA Registers

The programmable logic required on ATCA-7470 resides in an FPGA. It implements special
functions as follows:

LPC Bus Interface

SPI interface connected to IPMC and SPI bit-stream flashes

Reset controller

Interrupt Masking, Routing, and support of SERIRQ

Serial Line Routing

Telecom Clock Supervision Unit

Miscellaneous Registers (Post Code Register, Version Register)

SPI boot flash control, Boot device selection control

Support of several board control / status signals

Port80 7Seg-Debug Led control

COM Port routing:

Port 1: Faceplate or RTM

Port 2: IPMC Serial over LAN

Some of the internal functions are connected to the LPC bus via the corresponding bus
interface to the internal local bus and some other internal functions are connected to the IPMC
SPI interface.

For re usability reasons, the programmable logic is written in Verilog HDL. For details, refer to
the ATCA-7470 Glue Logic FPGA Design Specification.
