QSPI enable. When set, the QSPI initiates transfers in master mode by executing commands in the
command RAM. Automatically cleared by the QSPI when a transfer completes.The user can also clear this
bit to abort transfer unless QIR[ABRTL] is set. The recommended method for aborting transfers is to set
