Remarks 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.

Remarks 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.

Remarks 3.

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

#include    "r_cg_macrodriver.h"

Remark

m is the unit number, and n is the channel number.
