IrDA Port Not Working
If you are using the IrDA transceiver on the eZ80F91 Module, ensure that
the hardware is set up as follows:
1. to enable the control gate that drives the IrDA device, turn OFF
Jumper J9 on the eZ80Acclaim! MDS Adapter Board.
2. Set port pin PD2 Low. When this port pin and Jumper J9 are turned
OFF, the IrDA device is enabled.
3. Disable the RS-232 output by installing a shunt on jumper J8 on the
eZ80Acclaim! MDS Adapter Board.
