hi all, 

 

How to clear SPISR_SPTEF bit?

 

 DATASHHET the following description:

 

 If set, this bit indicates that the transmit data register is empty. To clear
this bit and place data into the transmit data register, SPISR has to be read with SPTEF = 1, followed by a write
to SPIDR. Any write to the SPI Data Register without reading SPTEF = 1, is effectively ignored.

 

Can provide some routine? thank you!
