Frequency Agile Transceiver
Data Sheet
7.2.2. AMIS-53000 in Slave Mode
The AMIS-53000 cannot be the slave for streaming data. The requirements of adding header information such as preamble or SOF
requires that the AMIS-53000 be in control of the data interface transfer. The receiver has similar requirements with removing the
header information.
As the slave for the data interface, the AMIS-53000 will simply issue an interrupt to the external host indicating data is available after a
data packet has been received.
For buffered transmit operation, the AMIS-53000 will issue an interrupt indicating it is ready to load the packet. After the packet is
received by the AMIS-53000, the transmitter is enabled, any packet formatting is done and the packet is sent.
7.2.3. Manchester Operation
Figure 47: Manchester Coded Data
If the Manchester option is selected in the data rate and format register, the AMIS-53000 will internally encode and decode both
transmit and receive data respectively. The format for the signal interface remains NRZ in this mode.
Table 100: Register Configuration Bits
7.2.4. Packet Framing
Three options bits located in the general options A register determine the method with which the transceiver will process packets: use
ID, length of packet (LOP) enable and cyclic redundancy check (CRC) enable. An additional bit in the TX config register enables the
buffered TX mode of operation.
