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.
CS4953x4/CS4970x4 System Designer’s Guide should be consulted for the firmware speed limitations.
