2.3.4 Flash Memory
Some of the ’C2xx devices feature on-chip blocks of flash memory, which is
electronically erasable and programmable, and non-volatile. Each block of
flash memory will have a set of control registers that allow for erasing, pro-
gramming, and testing of that block. The flash memory blocks can be selected
during reset by driving the MP/MC pin low. If the flash memory is not selected,
the device starts its execution from off-chip memory.
