Function
Address Bit 29
(Intel non-parity/Motorola) tristate when
unused.
Data Parity 1 (Intel parity mode),
bidirectional tristate line containing/
expecting parity bit of D(15:8)
Address Bit 28
(Intel non-parity/Motorola) tristate when
unused
Data Parity 0 (Intel parity mode),
bidirectional tristate line containing/
expecting parity bit of D(7:0)
Address Bus
tristate when unused.
Byte Enable (Intel bus mode)
The MUNICH32 provides word and long
word transfer. The byte enables determine
the address offset to the address
A31 … A2, the actual word has been
stored to.
Address Offset Size (Motorola mode)
Indicates the number of bytes remaining to
be transferred for this access. These
signals define the active sections of the
data bus.
In both cases these signals are tristate
when unused.
See Chapter 2.2 for details.
