25.9.3 RF Test Commands
In Table 25-12, there are listed some commands for modem test purposes. No registers are programmed
by the LLE based on these commands, so all registers must be set up by the MCU. This includes the
frequency word, which is otherwise written by the LLE; see Section 25.5 on how to program this. These
commands take no parameters, and do not cause the LLE to create any interrupts or to write any end
cause.
