Constants for manipulating the six digital strobe outputs.
Six digital strobe outputs are available. One is pre-configured as a read strobe, another is pre-configured as a write strobe while the other four can be set to a high or low logic level. These strobe lines enable external devices to synchronize with the digital data port and multiplex the eight digital input/output bits to wider bit widths.
The RD and WR bits set the inactive state of the read and write strobe outputs. Thus, if these bits are set to 0, the strobe outputs will pulse high.
