Description
G2
DI_SCAN
TID
Scan output drive inhibit (tie high to VDD-IO (2.5 V) for
functional operation). This input has an internal pull-
down resistor.
G4
H1
PUDI
PON
TI
Pull up/down inhibit for LVTTL receivers (tie low for
functional operation).
TIU
CMOS(test)/LVDS mode selection for LVDS receivers
(tie high to VDD-IO (2.5 V) for functional operation). This
input has an internal pull-up resistor.
G1
SE
TID
TID
TO
Scan enable (tie low for functional operation). This
input has an internal pull-down resistor.
H3
TEST_MODE
SCANOUT0/MBISTGO
Test mode enable (tie low for functional operation).
This input has an internal pull-down resistor.
W34
Scan chain output. Must be left unconnected for
functional (non-scan) operation.
In MBIST mode, MBISTGO indicates MBIST has not
detected an error.
