Microgate SyncLink - General Purpose I;O Signals

General Purpose I/O Signals
A 14 pin header (J2, Molex PN 87832-1420) provides 12 general purpose input/output signals (GPIO[0]
to GPIO[11]) for application specific use. Applications configure, control and monitor these signals with
the serial API. Each signal may be configured as an input (power on default) or output. GPIO signals are
3.3V TTL compatible and inputs are 5V tolerant. Exceeding specifications can damage the card.
