Table 25.4 Chip-Level (Global) Configuration Registers (continued)
Configuration Address Bytes are used. There is no restriction on the address chosen,
except that A0 is 0, that is, the address must be on an even byte boundary. As soon as
both bytes are changed, the configuration space is moved to the specified location with no
delay ( Note: Write byte 0, then byte 1; writing CR27 changes the base address).
