Infrared Encoder/Decoder
Overview
The Z8F640x family products contain two fully-functional, high-performance UART to
Infrared Encoder/Decoders (Endecs). Each Infrared Endec is integrated with an on-chip
UART to allow easy communication between the Z8F640x family device and IrDA Phys-
ical Layer Specification Version 1.3-compliant infrared transceivers. Infrared communica-
tion provides secure, reliable, low-cost, point-to-point communication between PCs,
PDAs, cell phones, printers and other infrared enabled devices.
