Starts DALI data reception.
Remark 1. This API function performs byte-level DALI reception the number of times specified by the argument rx_num, and stores the data in the buffer specified by the argument rx_buf.
Remark 2. Actual DALI reception starts after this API function is called, and R_DALIn_Start is then called.
[Syntax]
#include r_cg_macrodriver.h
MD_STATUS R_DALIn_Receive ( uint8_t * const rx_buf, uint16_t rx_num );
Remark n is the channel number.
