Note 1: If the USER-CONFIGURED option has been selected (see Section 4.10), add the configured A24 base
address to the start and end addresses of the A24 address range and the configured A16 base address
to the start and end address of the A16 address range. Refer to Table 4-3, in Section 4.10.
Note 2: If, after addition of the configured A24 base address, the A24 address range for a 575 secondary
would contain an address greater than EFFFFF
16
, then that 575 secondary cannot be installed.
Note 3: Addresses are fixed. Do not add the A24/A16 base address to these addresses.
Note 4: This address range is used if any 575 VMEbus I/O module is installed.
