The 3-wire S-bus at the radio side is a 32-bit serial interface which is used for control, TX/RX and channel information.
The 32-bit definition is given in Tables 4 and 5.
Bits 31 to 9 are static values and will not change dynamically, the value for these bits come from the static registers. Only
the trx and main divider fields will control the UAA3558 on a slot-by-slot basis. The trx and main divider information comes
from the baseband controller serial interface channel word; see Section 6.5.1. However, the baseband controller channel
information needs a conversion to get the correct main divider information for the UAA3558.

6.4.2
The JTAG serial interface is used to control the PCF26100 and subsequently the radio. The PCF26100 must be the only
slave on the JTAG bus as the PCF26100 does not allow for multi-slave operation. The JTAG interface protocol used is
fully compliant with the standard set out in “IEEE Std 1149.1-1990” . The following features are supported:
The JTAG interface allows for 2 ways of accessing a register. One is the communicate address and data, and the second
one is for successive accesses to the same registers where only the data is communicated. This can, for example, be
used for updating the channel information before every packet.
