Starts CSI data transmission/reception.

Remark 1.      This API function repeats the byte-level CSI transmission from the buffer specified in argument tx_buf the number of times specified in argument tx_num.

Remark 2.      This API function performs byte-level CSI reception the number of times specified by the argument tx_num, and stores the data in the buffer specified by the argument rx_buf.

Remark 3.      When performing a CSI reception, R_CSImn_Start must be called before this API function is called.
