4.1 General-Purpose I/O (GPIO, IOMUX)

MSPM0 GPIO functionality covers all of the features offered by the S32K1xx , KEA128x devices, and KM35x with additional functionality. NXP uses the term GPIO to refer to the pins that can be set, reset, or toggle. However, MSPM0 uses a slightly different nomenclature, namely:

  • MSPM0 GPIO refers to the hardware capable of reading and writing IO, generating interrupts, and so forth.
  • MSPM0 IOMUX refers to the hardware responsible for connecting different internal digital peripherals to a pin. IOMUX services many different digital peripherals, including, but not limited to, GPIO.

The MSPM0 GPIO and IOMUX modules cover the same functionality as NXP's GPIO, PORT, and TRGMUX/SMU modules. MSPM0 devices also offer several additional functions that are unavailable for NXP S32K1xx, KEA128x, and KM35x devices.
