5.6.13 Bus Configuration Register
The first write to the ISCC after a hardware reset is always to the Bus Configuration Reg-
ister. The register is shown in Figure 5-38. The Bus Configuration Register is not affected
by any reset function other than a hardware reset and is accessible only after the hardware
reset. Note that when writing to the Bus Configuration Register, /AS and A1/A//B are used
to program certain bus interface features. Refer to the Bus Interface Unit description for
details.
