Serial Ports & Other DSP I/O

The DSP contains various I/O ports. These signals are connected to a 0.1” pitch DIL
pin header. The pin-out of this connector is shown here:

FPGA configuration

The CPLD and the FPGA have two different JTAG chains. You can configure the
FPGA by the JTAG connector using for instance the Xilinx parallel cable IV.

The lines M0, M1 and M2 are not connected to the CPLD. These lines are hardwired
connected to the FPGA at high-logic level ‘1’. So, the FPGA is configured in Slave
Serial mode.
