The Transmitter Command Register TCMDR contains the command codes that are used
during Command Frame transmission. Each time one of the CMDPx bit fields is written,
a Command Frame transmission is triggered. Independent of the transferred command
code value, a Command Frame transmitted event can be generated in the transmitter for
each pipe and a Command Frame received event for each pipe in the receiver,
respectively.
