Comments

User should call this function periodically until the whole operation finishes.

This function can also be called inside an interrupt procedure for program/erase to take the

full advantage of interrupt. Each time the interrupt procedure is called, ‘FlashCheckStatus’

gets called to continue to complete the whole operation.

Assumptions

It assumes that the Flash block is initialized using a ‘FlashInit()’ API.
