XE1283 is not only made of an XE1203F and an XE8806A/XE8807A integrated together: it also includes internal
connections - the API bus, which reduces schematic, layout, and software development by ensuring compatibility with the
free API developed by Semtech.
These connections are illustrated in the figure below:
This bus enables one to send/receive RF data through the BitJockey™ and write/read the transceiver’s configuration
registers.

INTERNAL CONNECTIONS (API BUS)
http://www.semtech.com
Pin DATA of the XE1203F is used in unidirectional mode
Pin PD2 of the BitJockey™ is used as pattern detection input
The BitJockey™’s PCM Encoder/Decoder should be programmed for NRZ data.
Port B which has miscellaneous analog capabilities is kept completely available unless a Tx/Rx antenna
switch is going to be driven.
Like all the remaining pins of both chips, the internal connections are also bonded out for debug and flexibility
purposes.
