Section 21 FSI Interface
21.4.4
1. Set the FSI enable bit FSIE (in FSICR1) to 1 and set the communications mode bits CPHS and
2. Set the FSI receive enable bit RE (in FSICR2) to 1 and select the communications clock.
3. Set the number of bytes to be transmitted and received (FSIBNR) and write the transmit data
4. Set the FSI instruction register (FSIINS).
FSIRXI
21.4.5
After the FSI communications operation has started, the FSI issues a communications operation
according to the communications settings. The communications settings must not be changed until
the communications operation has completed. To change communications settings, such as
communications mode, communications clock, and number of bytes to be transmitted or received,
wait until completion of the communications operation and then change the communications
settings.
