R/W The VGA_RESET_N signal is used to reset the peak
detectors in the VGA in the RX chain.

R/W Reserved, read as 0
1
R/W The BALUN_CTRL signal controls whether the PA should
receive its required external biasing (1) or not (0) by
controlling the RX/TX output switch.
1
R/W RXTX signal: controls whether the LO buffers (0) or PA
buffers (1) should be used.
1
R/W Powerdown of prescaler.
1
R/W Powerdown of PA (negative path).
1
R/W Powerdown of PA (positive path). When PA_N_PD=1 and
PA_P_PD=1 the up conversion mixers are in powerdown.
1
R/W Powerdown of TX DACs.
