PE1 and PE2 encoding details are found in Table 5.
Note that during normal receive and transmit operation that
PE1 is static and PE2 toggles for receive and transmit
states.

NOTE: PLL_PE is controlled via the serial interface, and can be
used to disable the internal synthesizer, the actual synthesizer con-
trol is an AND function of PLL_PE, and a result of the OR function of
PE1 and PE2. PE1 and PE2 will directly control the power enable
functionality of the LO buffer(s)/phase shifter.
