The PIC32CXMTSH-DB board is equipped with five user buttons. The push buttons consist of
momentary push button switches mounted directly on the board. When any switch is
depressed, it will cause low (zero) to appear at the associated input pin.
- Reset. Besides the reset conditions managed by the Reset Controller peripheral of the PIC32CXMTSH, such as Power-on Reset and brown-out monitor, a user can manually reset the PIC32CXMTSH by using the Reset push button, SW1.
- Force Wake-Up. Wake up from Backup mode can be done through the Force Wake-up (FWUP) pin by pushing the push button SW2.
- Tamper. Tamper button SW3 allows simulating a tampering event. This pin can also be used as a wake-up function.
- Scroll-Up and Scroll-Down. Scroll-Up and Scroll-Down buttons SW4 and SW5 are used in the pre-programmed Demo Meter application to navigate through the menu.
