12.2.4.5 Hardware and Software Constraints
The NVM drivers use several PIOs in peripheral mode to communicate with external memory devices. Care must be
taken when these PIOs are used by the application. The devices connected could be unintentionally driven at boot time,
and electrical conflicts between output pins used by the NVM drivers and the connected devices may occur.
To assure correct functionality, it is recommended to plug in critical devices to other pins not used by NVM.
Table 12-4 contains a list of pins that are driven during the boot program execution. These pins are driven during the boot
sequence for a period of less than 1 second if no correct boot program is found.
Before performing the jump to the application in internal SRAM, all the PIOs and peripherals used in the boot program
are set to their reset state.
