Because my MCU has not enough SPI pins so I can only use I/O pins as control SPI.But I'm not sure that the way of the IO pins simulate SPI.Should I send a pluse(0),follow it send a datum then send another pluse(1).At I/O port,I can only send a datum at the same time and can not send a byte or two byte data?

I want to use an I/O port to control an SPI clock and its data.
