Hi All, Consider a LPC2124 in Slave mode. What is the effect of pulling the /SSEL line high (called DATA ABORT) during an SPI transmission. What is the effect on the SPI Tx and Rx registers. If you wanted to re-start SPI transmissions some time after (make /SSEL low and start the SPI transmission). Would you expect the the SPI registers to be unchanged. IE what is the effect on ...
