3.2.13 Fapi_getFsmStatus()

Returns the value of the STATCMD register.

Synopsis

Fapi_FlashStatusType Fapi_getFsmStatus(void)

Parameters

None

Description

This function returns the value of the STATCMD register. This register allows the user application to determine whether an erase or program operation is successfully completed or in progress or suspended or failed. The user application should check the value of this register to determine if there is any failure after each erase and program operation.
