Transmit Load. A positive-going edge loads the pattern generator with
the contents of the Pattern Set Registers. The MSB of the repetitive or
pseudorandom pattern appears at TDATA after the third positive edge of
TCLK from asserting TL. TL is logically OR’ed with PCR.7 and should
be tied to V
Data Bus. An 8-bit multiplexed address/data bus.

Signal Ground. 0.0V. Should be tied to local ground plane.
Positive Supply. 3.3V.
Bus Type Select. Strap high to select Motorola bus timing; strap low to
select Intel bus timing. This pin controls the function of the
ALE(AS), and
function listed in parenthesis ().
Read Input (Data Strobe).
Chip Select. Must be low to read or write the port.
Address Latch Enable (Address Strobe). A positive going edge serves
to demultiplex the bus.
Write Input (Read/Write).
Alarm Interrupt. Flags host controller during conditions defined in
Status Register. Active low, open drain output.
Positive Supply. 3.3V.
Signal Ground. 0.0V. Should be tied to local ground plane.
Load Count. A positive-going edge latches the current bit and bit error
count into the user accessible BCR and BECR registers and clears the
internal count registers. LC is logically OR’ed with control bit PCR.4.
Should be tied to V
Receive Loss Of Sync. Indicates the real time status of the receive
synchronizer. Active high output.
