Functional Description

Access To The Control Register Map
Write-only access to the control register map is enabled by applying the SCR command asserting the CRE-pin to
high. In combination with CRE set to high, Pin A19 designates the operation to one of either control registers.
Pin A19 set to low selects the Refresh Control Register (RCR), Pin A19 set to high addresses the Bus
Configuration Register (BCR).
Write and read access to the control registers is also available at S/W entry method. For details, please refer to
“Appendix B: S/W Register Entry Mode (“4-cycle method”)” on Page 51
