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