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

MSPM0 GPIO functionality covers almost all the features provided by STM8S and STML series. STM8 uses the term Pin Functions and Port Function to refer to all the functionality responsible for managing the device pins, generating interrupts, and so forth. Here is the description of MSPM0 GPIO and IOMUX function:

  • 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.

Together MSPM0 GPIO and IOMUX cover the same functionality as STM8 GPIO. Additionally, MSPM0 offers functionality not available in STM8L and STM8S series devices such as DMA connectivity, controllable input filtering and event capabilities.
