commands are issued during Transmit Conversion Periods A, B, and C, the first two commands may cause
Receive Conversion Periods A and B to be adjusted, while the third receive adjustment command is ignored.
The third adjustment command is ignored since it was issued during Receive Conversion Period B, which
already will be adjusted via the Transmit Conversion Period B adjustment command.

asynchronous operation – more than one set of primary and secondary DX serial communication
occurring between two receive frame sync (see AIC DX data word format section)
The TA, TA’, TB, and control register information that is transmitted in the secondary communications is always
accepted and is applied during the ongoing transmit conversion period. If there is sufficient time between t₁ and
t₂, the TA, RA’, and RB register information, which is sent during Transmit Conversion Period A, will be applied
to Receive Conversion Period A. Otherwise, this information will be applied during Receive Conversion Period
B. If RA, RA’, and RB register information has already been received and is being applied during an ongoing
conversion period, any subsequent RA, RA’, or RB information that is received during this receive conversion
period will be disregarded (see diagram below).
