Hello TI Community,
I would like to know if the following is possible?
Regarding the SPI Module. Can the Tx FIFO Register be filled up with 16 bit words (16 x 16 stack) and automatically transmit these words without the MCU assistance?
I would like to transmit 4 16-bit words to an external SPI DAC for monitoring purposes. At the moment it is setup to transmit 1 word at a time and the program waits for each word to be transmitted. It would be helpful if the 4 words are written to the Tx FIFO Register and the SPI module transmits all four words by itself so the MCU can go off and do something else. Is this possible to do? If not then what is the Tx FIFO register used for? I might have mis-interpreted the functionality of the Tx FIFO register.
Thank you
Glen
