Detailed Description
User SIP Header
The SP605 includes a 6-pin single-inline (SIP) male pin header (J55) for FPGA GPIO access.
Four pins of J55 are wired to the FPGA through 200Ω series resistors and a level shifter, and
the remaining two J55 pins are wired to 3.3V and GND. The J55 header is described in
Figure 1-18 and Table 1-26.

Notes:
1. Each GPIO_HEADER_n signal is sourced from the FPGA as
<netname>_LS to a level shifter, then to the J55 header.
2. Each GPIO_HEADER_n net has a 200Ω series resistor between the
level shifter and its respective header pin.
