RSTB
Input
B9
Address Bus (A[10:0]). The address bus
A[10:0] selects specific registers during
S/UNI-QJET register accesses.

Input
Input
Active low Reset (RSTB).This signal is set
low to asynchronously reset the
S/UNI-QJET. RSTB is a Schmitt-trigger
input with an integral pull-up resistor.
ALE
A8
Address Latch Enable (ALE). The address
latch enable (ALE) is active-high and
latches the address bus A[10:0] when low.
When ALE is high, the internal address
latches are transparent. It allows the
S/UNI-QJET to interface to a multiplexed
address/data bus. ALE has an integral
pull-up resistor.
INTB
TCK
Output A7
Active low Open-Drain Interrupt (INTB).
This signal goes low when an unmasked
interrupt event is detected on any of the
internal interrupt sources. Note that INTB
will remain low until all active, unmasked
interrupt sources are acknowledged at
their source.
Input
B6
Test Clock (TCK).This signal provides
timing for test operations that can be
carried out using the IEEE P1149.1 test
access port.
