TSPC106
2102B–HIREL–02/02
L2 Cache/Multiple
Processor Interface
Signals
The TSPC106 provides support for either an internal L2 cache controller or an external
L2 cache controller and/or additional 60x processors.
Internal L2 Controller Signals
Table 3 lists the interface signals for the internal L2 controller and provides a brief
description of their functions. The internal L2 controller supports either burst SRAMs or
asynchronous SRAMs. Some of the signals perform different functions depending on
the SRAM configuration.
TSIZ[0:2]
Transfer size
3
O
Specifies the data transfer size for the 60x bus transaction.
I
Specifies the data transfer size for the 60x bus transaction.
TT[0:4]
Transfer type
5
O
Specifies the type of 60x bus transfer in progress.
I
Specifies the type of 60x bus transfer in progress.
WT
Write-through
1
I/O
Indicates that an access is write-through.
XATS
Extended address
transfer start
1
I
Indicates that the 60x has started a direct-store access (using the
extended transfer protocol). Since direct-store accesses are not
supported by the TSPC106, the TSPC106 automatically asserts when
TEA and XATS are asserted (provided TEA is enabled).

I/O
For an asynchronous SRAM configuration, indicates bit 0 of the burst
address counter.

O
For an asynchronous SRAM configuration, indicates bit 1 of the burst
address counter.

O
For a burst SRAM configuration, indicates that the burst RAMs should
increment their internal addresses.
DALE
ADS
BRL2
Data address latch

1
O
For an asynchronous SRAM configuration, indicates that the external
address latch should latch the current 60x bus address.
DCS
BG3
Data RAM chip
select
1
O
Enables the L2 data RAMs for a read or write operation.
DIRTY_IN
BR1
Dirty in
1
I
Indicates that the selected L2 cache line is modified. The polarity of
DIRTY_IN is programmable.
DIRTY_OUT
BG1
Dirty out
1
O
Indicates that the L2 cache line should be marked as modified. The
polarity of DIRTY_OUT is programmable.
