3.9.5 General Purpose Input/Output Header
The following table in Section 19, “J2D2 GPIO Header Definition” on page 39 shows the GPIO
signal assignments. The GPIO signals are muxed with the serial port signals. The serial port must be
disabled to use the GPIO signals. These pins corespond to Jumer J2D2.
