Other Parts Discussed in Thread: TM4C1231H6PGE

I use TM4C1231H6PGE.

I need to use SSI2 (master) with uDMA. I setup both RX and TX channels, and I want the EOT interrupt.

I cannot find in the registers how to program the EOT interrupt.

Hello Max,

The EOT bit in SSICR1 register when set makes the TXMIS to behave a an EOT Interrupt. If cleared then it only mirrors the TX FIFO Status

The TXMIS (also if it behaves as EOT) is masked by DMA when DMA is activated on SSI, isn't it?

Hello Max,

The interrupt from the peripheral is masked not the interrupt status registers
