12.10 System Interface Addresses
Addressing Conventions
Addresses associated with doubleword, partial doubleword, word, or partial word transactions and update requests, are aligned for the size of the data element. The system uses the following address conventions:
- Addresses associated with block requests are aligned to double-word boundaries; that is, the low-order 3 bits of address are 0.
- Doubleword requests set the low-order 3 bits of address to 0.
- Word requests set the low-order 2 bits of address to 0.
- Halfword requests set the low-order bit of address to 0.
- Byte, tribyte, quintibyte, sextibyte, and septibyte requests use the byte address.
