Received Data Count Register
The RDCR indicates the number of good characters currently in the serial received data FIFO. Host
software can use this value as a loop counter when taking characters out of the FIFO. The value in
this register is only valid during the context of a service request acknowledge. At other times, it
may or may not give a true indication of the number of characters in the FIFO.
