Write Access Counter

The field NBWRA, in the Write Access Counter register (QSPI_WRACNT) defines the number of bytes to be sent to the memory before QSPI_ISR.LWRA rises, which indicates that the last byte has been transmitted. NBWRA is reset and begins counting after each start of the instruction frame. If QSPI_IFR.PROTTYP=3 and QSPI_IFR.HFWBEN=1, NBWRA is reset after setting QSPI_IFR.HFWBEN bit to 1 and counts data on every frame.
