Header
r_cg_serial.h
Declaration
MD_STATUS R_CSI00_Send_Receive(uint8_t * const tx_buf, uint16_t tx_num,
uint8_t * const rx_buf)
Description
Prepares the data buffer for CSI00 communication (transmission/reception) and sets
the first byte of the transmit data.
Arguments
uint8_t * const tx_buf
uint16_t tx_num
: Transmit data buffer pointer
: Transmit data size
uint8_t * const rx_buf
: Receive data buffer pointer
Return Value

Remarks
CSI00 error callback function
r_cg_serial.h
static void r_csi00_callback_error(uint8_t err_type)
This function is called when the CSI00 error occurs.
uint8_t err_type
: Error type
None
The sample code does not include the error processing. Add processing to the user
program as needed.
