SPI - usingInterrupts() not supported?

[oveggeland]

Hi,

I see that the AVR library for SPI enables the use of SPI.usingInterrupts() to pause interrupts while performing transactions (see https://github.com/arduino/ArduinoCore-avr/tree/321fca0bac806bdd36af8afbc13587f4b67eb5f1/libraries/SPI). Is there a reason why this is not implemented in this library? I am writing a Arduino R4 wifi program where this would be a very handy feature.

Best,
Oskar
