Function Documentation

MW_ClearCrcPeriodInterrupt()

void MW_ClearCrcPeriodInterrupt

(

void

)

Clears the flag indicating that a CRC scan period is done.

Note

If the periodic interrupt is enabled, the period flag must be cleared in order to continue CRC scan when re-entering Idle sleep mode.

Definition at line 33 of file midware_checksum_manager.c.

MW_GetClearCrcDoneError()

errFlag_t MW_GetClearCrcDoneError

(

void

)

Reads and clears the flag indicating a CRC scan of Flash is done and returns the scan result.

This function checks if a CRC scan has been completed and evaluates the result after a scan. If the DONE flag is not set, it returns no error. When the the DONE flag is set, the status register is read to check the result. An error is returned if either the ERROR or BUSY status flag is set. The DONE flag being set while the status is BUSY could indicate that a previous result was not checked before a new scan was initiated. Moreover, the OK status flag is invalid while BUSY is set.

Return values

ERROR	CRC scan of Flash detected an error or previous scan result lost.
NO_ERROR	CRC scan of Flash not done or scan of Flash detected no errors.
