You can't use that header for DIO when you've got SD-- its the SD
signals. If you wanted to you could attach a ribbon cable to it and
use it for an externally mounted SD card socket, buts thats it.
The CPLD on the TS-7260 is around 60% full after glue logic and the
third UART serial port (COM3). There are currently 3 separate
configurations of that last remaining space:
*) 5UART option, 2 extra TTL-only serial ports with TX enable signals.
This includes a very simple GPIO core (data direction register and
data register only).
*) XDIO option, uber-GPIO that can do quadrature, PWM,
freq-counter, pulse timing, IRQ and DRQ, etc...
*) SDCARD option, a special core for a SD interface. Requires a
special Linux driver module to be of use.
This is also the area we customize on a per-customer basis for some
really specific customer logic requirements.
