Does pinMode 'input' state place pin in tri-state mode for SPI multi device connectivity?

Wed 2019.07.10

Is the pin in tri-state mode?

pinMode 'input' - Digital input:

implies 'Yes' as the other two choices 'input_pullup' and 'input_pulldown' specify resistances.

p.31 Sec 3.27 of STM32 datasheet

' as input (floating, with or without pull-up or pull-down) '

http://www.espruino.com/datasheets/STM32­F401xD.pdf

Arduino documentation is specific, e.g. Yes for input mode.

The real question, when connecting multiple devices using SPI, does the device acting as a slave, or a device no longer acting in SPI mode, pins have to be placed in the 'input' mode when at idle?
