Operational Description
eZ80L92 Development Kit
User Manual
The eZ80L92 Module features an Infrared Encoder/Decoder register that
configures the IrDA function. This register is located at address
the internal I/O register map.
The Infrared Encoder/Decoder register contains three control bits. Bit 0
enables or disables the IrDA encoder/decoder block. Bit 1, if it is set,
enables received data to pass into the UART0 Receive FIFO data buffer.
Bit 2 is a test function that provides a loopback sequence from the TxD
pin to the RxD input.
Bit 1, the Receive Enable bit, is used to block data from filling up the
Receive FIFO when the eZ80L92 Module is transmitting data. Because
IrDA data passes through the air as a light source, transmitted data can
also be received. This Receive Enable bit prevents this data from being
received. After the eZ80L92 Module completes transmitting, this bit is
changed to allow for incoming messages.
The code below provides an example of how this function is enabled on
the eZ80L92 Module.
