Sure!
It's pretty common in microcontrollers because it uses very few lines for communication, yet can run at decent speeds.
I'm not sure if/where there is an official specification but this page has a nice explanation:

The major benefit is that much smaller packages are possible (board land is precious) since the protocol needs (much) fewer signals.
