Section 21 FSI Interface

Interrupt Sources

The FSI has four interrupt sources for the slave (this LSI): FSITEI, FSIRXI, FSICMDI, and

FSIWI. FSITEI is a transmit end interrupt when the slave executes the SPI flash memory write

transfer. FSIRXI is a receive end interrupt when the slave executes the SPI flash memory read

transfer. FSICMDI is a command receive interrupt in host FSI command write. FSIWI is a write

receive interrupt in the case of write from the host to the SPI flash memory. Setting the

corresponding enable bit to 1 enables the relevant interrupt request to be issued.
