Hello,
We have a little question about the usage of SPI links of the TMS570LC4357.
We use the SPI link in master mode.
On our board the external SPI component never send any serial data, we only make write access into this component.
(SIMO is used, but SOMI is not used on the board).
Therefore RXBUF / SPIBUF are useless for us.
We periodically send SPI data to the external component by writing into the SPIDAT1 register but we plan to never read the SPIBUF register and to ignore the bits of the SPIFLG register associated to it.
We guess that the SPIBUF will overflow since we never read it but we don't mind about that.
Can we proceed this way ?
Is there any issue or side effects in never reading the SPIBUF ?
Thank you.
Regards
Patrick
