Figure 16. Infrared Data Communication System Block Diagram
The Z8 Encore! XP
high-performance UART to Infrared Encoder/Decoder (Endec). The Infrared Endec is
integrated with an on-chip UART to allow easy communication between the Z8 Encore!
and IrDA Physical Layer Specification, Version 1.3-compliant infrared transceivers.
Infrared communication provides secure, reliable, low-cost, point-to-point communication
between PCs, PDAs, cell phones, printers, and other infrared enabled devices.
Figure 16
When the Infrared Endec is enabled, the transmit data from the associated on-chip UART
is encoded as digital signals in accordance with the IrDA standard and output to the
infrared transceiver through the TXD pin. Likewise, data received from the infrared
transceiver is passed to the Infrared Endec through the RXD pin, decoded by the Infrared
