TM4C data sheet error and tivaware library whose fault?

Hello,

It's not actually an error but that the TivaWare definitions are using a slightly different convention that is more aligned with Industry standard views.

The datasheet is indicating the empty levels of the FIFO while TivaWare definitions are indicating the full levels of the FIFO. Most users think of FIFO interrupts from a standpoint of 'how full is my FIFO' and therefore the TivaWare definitions were written with that mentality in mind.

You'll see 7/8 empty maps to 1/8 full, 3/4 empty maps to 1/4 full etc.

Best Regards,
