SPI questions

I'm using F3 and L4 processors and have a few spi questions

1)  In half-duplex mode, how do you receive a single byte with a master ?  two bytes ?  It appears from reading that in this case, the SPI clock runs as long as one is in receive mode which begs the question -- how do you reliable stop on a byte boundary ?  This sounds like a designed in race condition.

2)  Can you change the data size while the SPI is enabled (but not in the middle of communicating) ?
