WebMay 5, 2024 · SPI are D11-12-13 on any '328 based Arduino. They are hardware in the '328 chip and cannot move.* The only thing you can do is select a different chip select pin; D10 must be set as an output (and can be connected & used with some other device if you want). WebThe HOLD pin is used in conjunction with theCS pin to select the AT25010A/020A/040A. When the device is selected and a serial sequence is underway, HOLD can be used to pause the serial communication with the master device without resetting the serial sequence. To pause, the HOLD pin must be brought low while the SCK pin is low.
