Hardware and Software Constraints
Table 13-6.
Note:
The MCI, the SPI and NAND Flash drivers use several PIOs in alternate functions to communi-
cate with 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
peripherals output pins and the connected devices may appear.
To assure correct functionality, it is recommended to plug in critical devices to other pins.
Table 13-7
are driven during the boot sequence for a period of less than 1 second if no correct boot program
is found.
For the DataFlash driven by the SPCK signal at 8 MHz, the time to download 72 KBytes is
reduced to 200 ms.
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.
