SCP_CLK frequency1
1. The specification fiicck indicates the maximum speed of the hardware. The system designer should be aware that
the actual maximum speed of the communication port may be limited by the firmware application. Flow control
using the SCP_BSY pin should be implemented to prevent overflow of the input data buffer.
