None.

Comments

This function resumes one operation if there is any operation is suspended. For instance, if

a program operation is in suspended state, it is resumed. If an erase operation is in

suspended state, it is resumed too. If an erase-suspended program operation is in

suspended state, the program operation is resumed prior to resuming the erase operation. It

is better to call this function based on suspendFlag returned from ‘FlashSupend()’.

Following table defines and describes various resume states and associated resume codes.

Assumptions

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