and when it does, it never correctly transmits the data it is supposed to send, nor does the data collected in the RX buffer match what I see in the oscilloscope.

Possibly, instead of waiting for theRXNEflag when norx bufferis supplied it could wait for!TXE, like this: if (data->ctx.rx_buf){ // If a RX buffer was supplied it means the user is expecting to recieve something while (!ll_func_rx_is_not_empty(spi)) { /* NOP */ } } else{...
Interrupt conditions include: receiver errors, available receiver buffer data, transmit buffer empty, or when a modem status flag is detected. IOR 21 24 19 I Read strobe (Active-LOW strobe). A logic 0 transition on this pin will load the contents of an internal register defined by address ...

Interrupt conditions include: change of state of the input pins, receiver errors, available receiver buffer data, available transmit buffer space, or when a modem status flag is detected. An external resistor (1 kΩ for 3.3 V, 1.5 kΩ for 2.5 V) must be connected between this pin and ...
It appears that there is no DMA error, no UART error, DMA has completed and the FIFO is empty. The TC complete flag is set and TCIE is reset suggesting that the interrupt had occurred but the responseCompleteFunction had not been called?? Here are the contents of the regis...
