IWR1443BOOST: txChannelEn parameter of channelCfg

Hi,

My question concerns txChannelEn parameter of channelCfg command.

I found that codes 1, 3, 5 and 7 are valid for IWR1443BOOST. It says Error -1 for codes 2, 4 and 6.
First datasheet page of IWR1443 says that Two of Three Transmit Channels can be used simultaneously.
But mmwave_sdk_user_guide.pdf Table 1 on page 20 says: “ The azimuth and elevation antennas can be enabled using bitmask 0x7”

Is all three transmit channels works simultaneously when I set txChannelEn = 7 ?
