3.11 MVIO - Multi-Voltage I/O
3.11.1 Introduction
The MCC Melody MVIO PLIB Driver (Peripheral Library) generates API to support MVIO-specific peripheral functionality on AVR ® DB and DD target MCU's.
The Multi-Voltage I/O (MVIO) module allows a subset of the I/O pins to be powered by a different I/O voltage domain, VDDIO2 while the rest of the I/O pins run on VDD.

3.11.4.1 MVIO
This file contains the API prototypes for the MVIO driver.
3.11.4.1.1 Module description
This file contains the API prototypes for the MVIO driver.
Typedefs
typedef void(* MVIO_cb_t) (void)
Function pointer to callback function called by the MVIO. The default value is set to NULL which means that no callback function will be used.
Functions
void MVIO_Vddio2CallbackRegister (MVIO_cb_t cb)
Registers a callback function to be called when an MVIO Interrupt event occurs.
int8_t MVIO_Initialize (void)
Initializes the MVIO module.
bool MVIO_isOK (void)
Checks if the VDDIO2 supply voltage is within the acceptable operation range.
3.11.4.1.2 Typedef Documentation
MVIO_cb_t
void * MVIO_cb_t
Function pointer to callback function called by the MVIO. The default value is set to NULL which means that no callback function will be used.
