12.6.1 Strict 60x-Compatible External Masters
Any 60x-compatible devices that use a 64-bit data bus can access the MSC8113 internal registers
and local bus. These devices can also use memory controller services under the following
restrictions, which apply only to system bus-assigned memory banks accessed by the external
device:
64-bit port size only
No ECC or RMW-parity
No data pipelining
For 60x bus compatibility, the following connections should be observed:
Connect MSC8113
TSZ[1–3]
to the external master
TSZ[0–2]
Pull down MSC8113
TSZ0
Pull up MSC8113
PSDVAL
12.6.2 MSC8113-Type External Masters
An MSC8113-type external master is a 60x-compatible master with additional functionality. It
has fewer restrictions than other 60x-compatible masters:
Any port size (64, 32, 16, 8)
ECC and RMW-parity
Data pipelining
12.6.3 Extended Controls in 60x-Compatible Mode
In 60x-compatible mode, the memory controller provides extended controls for the glue logic.
The extended controls consist of the following:
Memory address latch (
ALE
) to latch the system bus address for memory use
The address multiplex signal (
PGPL5
/
PSDAMUX
), which controls external multiplexing for
DRAM and SDRAM devices.
PSDAMUX
is also available externally in single MSC8113
mode.
LSB address lines (
BADDR[27–31]
) for incrementing memory addresses
PSDVAL
as a termination to a partial transaction (such as port-size beat access).
Internal SDRAM bank selects (
BNKSEL[0–2]
) to allow SDRAM bank interleaving, as
described in Section 12.2.6, BNKSEL Signals in Single-MSC8113 Bus Mode.
