Description
WRITE ENABLE. Active low
This pin enables the chip to write the value on the D[7:0] pins into the
selected register when CE is also low. This pin can also function as
RD/ CE if RD is held low. See for details.
CHIP ENABLE. Active low
This control strobe enables the read or write operation. The contents of
the register selected by A[7:0] will be output on D[7:0] when RD is low
and CE is low. If WR is low and CE is low, then the selected register will
be loaded with the contents of D[7:0].
TEST DATA OUT. Active high
TEST DATA IN. Active high with pull-up
TEST MODE SELECT. Active high with pull-up
TEST CLOCK. Active high. Tie low if JTAG is not used.
TEST RESET. Active low with pull-up
Asynchronous reset for TAP controller. Tie low or to MR if JTAG is not
used.
SCAN ENABLE. Active low with pull-up
Enables access to internal scan registers. Tie high. Used for
manufacturing test only!
