MDBT42Q page documentation clarification needed

Sun 2019.03.31

'referring to the software 'port' of the code to the nRF52, not a specific hardware port'

Thank you for the clarification @TomWS that does make more sense, however, your comment:

'the Espruino code only identifies one of each type of port even though the device supports up to 3 SPI, etc.'

now generates another question, that is where may I ask is the declaration device supports up to 3 SPI? Three is specific, but the note below the image indicates one h/w and infinite s/w SPI. I was attempting to understand where the h/w SPI is defined and for which pins.
