Read: Anytime. In emulation modes read operations will return the data from the external bus. In all other
modes the data is read from this register.
Write: Anytime. In emulation modes write operations will also be directed to the external bus.
The MMCCTL0 register is used to control external bus functions, i.e., availability of chip selects.
