TS-8150-PC104

From Technologic Systems Manuals

The PC/104 connector consists of two rows of pins labeled A and B, the numbering of which is shown below. The signals for the PC/104 interface are generated by a MAX240 PLD on the TS-8150. It converts the MUXBUS cycles from the SoM to PC/104 bus cycles and provides some GPIO pins for finer control of the PC/104 interface.

Any of the I/O labeled DIO_* can be controlled through manipulation of the TS-8150 registers directly. See the PC/104 interface section for more information on how the pins are driven.
