SNIP_CLASSIC_MEMIF_SECTION_9_3_Ea_Cancel

9.3 Ea_Cancel The following figure shows as an example the call sequence for a canceled Ea_Write service. This sequence diagram shows that Ea_Cancel is asynchronous w.r.t. the underlying hardware while itself being synchronous. «module» NvM «module» MemIf BSW Task (OS task or cyclic call) «module» Ea «module» MemAcc «module» Mem «Peripheral» EEPROM loop MemAcc_MainFunction
