Table 60 enumerates the BSPI transmit interrupt sources.

Receive interrupt sources

The following enumeration defines the BSPI receive interrupt sources. The RC_IR_SRCS is

defined in the file 71x_bspi.h as follows:

typedef enum

{

BSPI_RC_FNE,

BSPI_RC_FF,

BSPI_RC_DIS

} BSPI_IT_RC;

Table 61 enumerates the BSPI receive interrupt sources.
