1. The system designer should be aware that the actual maximum speed of the communication port may be limited by
the firmware application. Hardware handshaking on the PCP_BSY pin/bit should be observed to prevent
overflowing the input data buffer. AN288 CS4953xx /CS497xxx Firmware User’s Manual should be consulted for
the firmware speed limitations.
