3.0 Operating Modes
The TRC103 has 5 possible chip-level modes. The chip-level mode is set by MCFG00_Chip_Mode[7..5] , which
is a 3-bit pattern in the configuration register. Table 5 summarizes the chip-level modes:

*nSS_CONFIG has priority OVER nSS_DATA
**SDO is an output if nSS_CONFIG = 0 and/or nSS_DATA = 0
Table 6
The TRC103 transmitter and receiver sections support three data handling modes of operation:
?
?
?
Continuous mode: each bit transmitted or received is accessed directly at the DATA input/output pin.
Buffered mode: a 64-byte FIFO is used to store each data byte transmitted or received. This data is writ-
ten to and read from the FIFO through the SPI bus.
Packet handling mode: in addition to using the FIFO, this data mode builds the complete packet in
transmit mode and extracts the useful data from the packet in receive mode. The packet includes a pre-
amble, a start pattern (sync pattern), an optional node address and length byte and the data. Packet data
mode can also be configured to perform additional operations like CRC error detection and DC-balanced
Manchester encoding or data scrambling.
The Buffered and Packet data modes allow the host microcontroller overhead to be significantly reduced. The
DATA pin is bidirectional and is used in both transmit and receive modes. In receive mode, DATA represents the
demodulated received data. In transmit mode, input data is applied to this pin.
