InternalFlashC.nc - Internal flash implementation for telos msp platform. On the msp, the flash must first be erased before a value can be written. However, the msp can only erase the flash at a segment granularity (128 bytes for the information section). This module allows transparent read/write of individual bytes to the information section by dynamically switching between the two provided segments in the information section. Valid address range is 0x1000 - 0x107E (0x107F is used to store the version number of the information segment).
