1. The SPI2 and SPI3 interfaces give the flexibility to work in an exclusive way in either the SPI mode or the
I
2
S audio mode.
2. For the LQFP100 and BGA100 packages, only FSMC Bank1 and Bank2 are available. Bank1 can only
support a multiplexed NOR Flash memory using the NE1 Chip Select. Bank2 can only support a 16- or 8-
bit NAND Flash memory using the NCE2 Chip Select. The interrupt line cannot be used since Port G is not
available in this package.
