It is possible to abort configuration by pulling CSI_B Low in a given CCLK cycle, then switching RDWR_B Low or High in any subsequent
cycle for which CSI_B remains Low. The RDWR_B pin asynchronously controls the driver impedance of the D0 - D7 bus. When RDWR_B
switches High, be careful to avoid contention on the D0 - D7 bus.
