This function should be used together with ‘FlashResume’. If suspendState is

C55_PGM_SUS or C55_ERS_SUS or C55_ERS_SUS_PGM_SUS, then ‘FlashResume’

should be called in order to resume the operation.

The table below lists the Suspend State against to the Flash block status.

The values of EHV, ERS, ESUS, PGM and PSUS represent the C55 status at the entry of

‘FlashSuspend’.

0: Logic zero; 1: Logic one; X: Do-not-care.

Assumptions

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

2.7.10

FlashResume

Description

This function checks if there is any suspended erase or program operation on the C55

module, and resumes the suspended operation if there is any.

C55_ERS_SUS

The erase operation on

main array is in suspended

state.

Programming/Read operation

is valid on main array space.

C55_ERS_SUS_PGM_SUS

The erase-suspended

program operation is in

suspended state.

Only read is valid on main

array space.
