FTFA_FSTAT field descriptions (continued)Field DescriptionThe value of the MGSTAT0 bit for "command-N" is valid only at the end of the "command-N" executionwhen CCIF=1 and before the next command has been launched. At some point during the execution of"command-N+1," the previous result is discarded and any previous error is cleared.45.3.3.2 Flash Configuration Register (FTFA_FCNFG)This register provides information on the current functional state of the flash memorymodule.The erase control bits (ERSAREQ and ERSSUSP) have write restrictions. Theunassigned bits read as noted and are not writable.Address: 4002_0000h base + 1h offset = 4002_0001hBit 7 6 5 4 3 2 1 0Read CCIE RDCOLLIE ERSAREQ ERSSUSP 0 0 0 0WriteReset 0 0 0 0 0 0 0 0FTFA_FCNFG field descriptionsField Description7CCIECommand Complete Interrupt EnableControls interrupt generation when a flash command completes.0 Command complete interrupt disabled1 Command complete interrupt enabled. An interrupt request is generated whenever the FSTAT[CCIF]flag is set.6RDCOLLIERead Collision Error Interrupt EnableControls interrupt generation when a flash memory read collision error occurs.0 Read collision error interrupt disabled1 Read collision error interrupt enabled. An interrupt request is generated whenever a flash memoryread collision error is detected (see the description of FSTAT[RDCOLERR]).5ERSAREQErase All RequestIssues a request to the memory controller to execute the Erase All Blocks command and release security.ERSAREQ is not directly writable but is under indirect user control. Refer to the device's ChipConfiguration details on how to request this command.ERSAREQ sets when an erase all request is triggered external to the flash memory module and CCIF isset (no command is currently being executed). ERSAREQ is cleared by the flash memory module whenthe operation completes.0 No request or request complete1 Request to:1. run the Erase All Blocks command,Table continues on the next page...Chapter 45 Flash Memory Module (FTFA)KL27 Sub-Family Reference Manual , Rev. 5, 01/2016Freescale Semiconductor, Inc. 895
