Mode Select
This EVM allows for the device to switch from interfacing modes. When J1 is left unshunted or shunted at
position 2 and 3, the TL16C750E is in Intel mode. This requires lines CS, IOW, and IOR to be used to
read or write from the device. If positions 1 and 2 are shunted on J1, Motorola mode is selected and the
TL16C750E is requires CS and IOW to toggle for communication. Note that the IOR pin needs to be held
in a logic high state to avoid any device issues (this is done through the pull up resistor R2 on the PCB).
