Function
Lower 27 bits of address bus. (I/O)
Upper four bits of address bus (I/O), or byte write enable
signals (O)
Identifies the processor state and the address space of the
current bus cycle. (I/O)
Upper 16-bit data bus used to transfer byte or word data.
Used in 16-bit bus mode. (I/O)
Lower 16-bit data bus used to transfer 3-byte or long-word
data. (I/O)
Not used in 16-bit bus mode.
Parity signals for byte writes/reads from/to external memory
module. (I/O)
Parity signals for byte writes/reads from/to external memory
module or defines 16-bit bus mode. (I/O)
Indicates a parity error during a read cycle. (O)
Enables peripherals or DRAMs at programmed addresses (O)
or interrupt level 7 acknowledge line. (O)
Enables peripherals or DRAMs at programmed addresses.
(O)
DRAM column address select or interrupt level acknowledge
lines. (O)
Indicates that an external device requires bus mastership.
(I)
Indicates that the current bus cycle is complete and the
QUICC has relinquished the bus. (O)
Indicates that an external device has assumed bus
mastership. (I)
Identifies the bus cycle as part of an indivisible
read-modify-write operation (I/O) or initial QUICC
configuration select. (I)
Indicates that an internal device requires the external bus
(Open-Drain O) or initial QUICC configuration select (I) or row
address select 2 double-drive output. (O)
