External L2 Controller Signals
When an external L2 cache controller is used instead of the internal L2 cache controller,
four signals change their functions.
DOE
DBGL2
Data RAM output
enable
1
O
Indicates that the L2 data RAMs should drive the data bus.
DWE[0:2]
DBG2
DBG3
Data RAM write
enable
3
O
Indicates that a write to the L2 data RAMs is in progress. Multiple pins
are provided to reduce loading.
HIT
Hit
1
I
Indicates that the L2 cache has detected a hit. The polarity of HIT is
programmable.
TOE
DBG1
Tag output enable
1
O
Indicates that the tag RAM should drive the L2 tag address onto the
address bus.
TV
BR2
Tag valid
1
I/O
Indicates that the current L2 cache line should be marked valid. The
polarity of TV is programmable.
TWE
BG2
Tag write enable
1
O
Indicates that the L2 tag address, valid, and dirty bits should be
updated.

O
Indicates that the external L2 controller has been granted mastership
of the 60x address bus.
BRL2
ADS
DALE
External L2 bus
request
1
I
Indicates that the external L2 controller requires mastership of the 60x
bus for a transaction.
DBGL2
DOE
External L2 data
bus grant
1
O
Indicates that the external L2 controller has been granted mastership
of the 60x data bus.
HIT
External L2 hit
1
I
Indicates that the current transaction is claimed by the external L2
controller. The external L2 controller will assert AACK and TA for the
transaction.
