Description
Internal Test Signals:
SCAN_MODE
C22
I
N/A
Scan Mode. For LSI Logic test purposes only. This
pin has a static pull-down.
TEST_HSC
C23
I
N/A
Test Halt SCSI Clock. For LSI Logic test purposes
only. Pulled LOW internally. This signal can also
cause a full chip reset.
TEST_PD
A2
I
N/A
Test Power Down. For LSI Logic test purposes
only. This pin has a static pull-down.
TEST_RST/
C1
I
N/A
Test Reset. For LSI Logic test purposes only.
Pulled HIGH internally.

4 mA
Memory Output Enable. This pin is used as an
output enable signal to an external EPROM or
flash memory during read operations. It is also
used to test the connectivity of the LSI53C1000
signals in the “AND-tree” test mode.
JTAG Signals:
TCK
D1
I
N/A
Test Clock. This pin provides the clock for the
JTAG test logic. This pin has a static pull-up.
TMS
E3
I
N/A
Test Mode Select (TMS). The signal received at
TMS is decoded by the Test Access Port (TAP)
controller to control JTAG test operations. This pin
has a static pull-up.
TDI
E2
I
N/A
Test Data In. This pin receives the serial test
instructions for the JTAG test logic. This pin has a
static pull-up.
TDO
E1
O
4 mA
Test Data Out. This pin is the serial output for test
instructions and data from the JTAG test logic.
