3.4 Bytes, Bits and Symbols

Bytes, bits and symbols are used in Microchip’s product naming conventions. Ensure bits and bytes are used appropriately, as the coding can be different for both, for example, in Manchester coding where 1 bit is coded by two symbols.

The following are some of the important functions that use symbol-based data handling:

  • SFIFO usage as preamble buffer in TX mode
  • WUP and SFID pattern definition in EEPROM configuration
  • Signal check size setup in EEPROM configuration
  • Carrier check parameter in EEPROM configuration
  • Run-In and stop sequence Pattern in RX mode and TX mode

In transmit mode, the data FIFO is loaded byte-wise with the raw data. The configured coding is done in HW and handled automatically from the system. In receive mode, the received data will be decoded automatically from the HW, if it is enabled in the configuration. The resultant raw data are loaded to the data FIFO.
