Figure 18. Infrared Data Communication System Block Diagram
The Z8 Encore! XP
mance UART to Infrared Encoder/Decoders (Endecs). Each Infrared Endec is integrated
with an on-chip UART to allow easy communication between the Z8 Encore! XP
F64XX Series 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 18
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 infra-
red transceiver via the TXD pin. Likewise, data received from the infrared transceiver is
passed to the Infrared Endec via the RXD pin, decoded by the Infrared Endec, and then
passed to the UART. Communication is half-duplex, which means simultaneous data
transmission and reception is not allowed.
