Read anytime. Write anytime.
At reset, E Clock divided by 2 is selected.
SPR[2:0] — SPI Clock (SCK) Rate Select Bits
Read anytime. Write has no meaning or effect.
SPIF — SPI Interrupt Request
These bits are used to specify the SPI clock rate.
SPIF is set after the eighth SCK cycle in a data transfer and it is
cleared by reading the SP0SR register (with SPIF set) followed by an
access (read or write) to the SPI data register.
