3.2.12 Fapi_checkFsmForReady()

Returns the status of the Flash State Machine.

Synopsis

Fapi_StatusType Fapi_checkFsmForReady(void)

Parameters

None

Description

This function returns the status of the Flash State Machine indicating if it is ready to accept a new command or not. The primary use is to check if an Erase or Program operation has finished.

Return Value

  • Fapi_Status_FsmBusy (FSM is busy and cannot accept new command except for suspend commands)
  • Fapi_Status_FsmReady (FSM is ready to accept new command)
