Remark

This API function performs byte-level simple IIC master reception the number of times specified by the argument rx_num, and stores the data in the buffer specified by the argument rx_buf.

#include    "r_cg_macrodriver.h"

void    R_IICmn_Master_Receive ( uint8_t adr, uint8_t * const rx_buf, uint16_t rx_num );

Remark

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