These 5 registers for the selected transmitter port should be programmed with receiver’s Key Selection
Vector. TX_BKSV_1 is the LSB and TX_BKSV_5 is the MSB. TX_BKSV_5 should be written last, as it
triggers the authentication process.

These 8 registers for the selected transmitter port should be programmed with a 64-bit pseudo-random
value before triggering the authentication process. TX_AN_1 is the LSB and TX_AN_8 is the MSB.

These 5 registers are read only which hold transmitter’s Key Selection Vector for the selected
transmitter port. TX_AKSV_1 is the LSB and TX_AKSV_5 is the MSB. All five bytes should be read
from here and then written to the receiver. Byte 5 should be written last to the receiver, as it will trigger
authentication there. These 5 registers should not be read until TX_AKSV_RDY bit is 1.
