Remark

This API function repeats the byte-level simple IIC master transmission from the buffer specified in argument tx_buf the number of times specified in argument tx_num.

#include    "r_cg_macrodriver.h"

void    R_IICmn_Master_Send ( uint8_t adr, uint8_t * const tx_buf, uint16_t tx_num );

Remark

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