Posted on January 02, 2007 at 12:34In my application I'm using the SPI-interface of the ST7Flite29 only to send data. As I'm taking the sequence
while ((SPICSR & bit7) == 0); /* waiting for SPIF flag */
SPIDR = SR_value;
it works as espected on the chip: jointly clearing the SPIF-flag and writing to the SPIDR-register.
But using the ST7VD, I have to clear the SPIF flag separately before writing to the SPIDR.
e.g.
while ((SPICSR & bit7) == 0); /* waiting for SPIF flag */
SPIDR;
SPIDR = SR_value;
If any moderator attaches importance to this fact, he might forward it to the ST7VD-team.
