DESCRIPTION
RST
11
O
This is the qualified active-low reset signal. RST has a fail-safe open-drain output.
RTS
35
U
O
Request to send is an active-low signal. When active, RTS informs the modem of the data set
that the UART is ready to receive data. RTS is set to its active state by setting the RTS modem
control register bit and is set to its inactive (high) state either as a result of a reset, doing
loop-mode operation, or by resetting bit 1 (RTS) of the MCR.

S
I
When SSAB is high, this is the subsystem address bus and SAD (7–0) is the subsystem data
bus. When SSAB is low, this bus is not used and SAD(7–0) is the subsystem multiplexed
address/data bus.

Address bit 8 is bit 8 of the subsystem address bus.

S
I/O
Subsystem address/data 7–0. This is a multiplexed bidirectional address/data bus to the
attribute-memory DPRAM and CCRs when SSAB is low. This becomes a bidirectional data bus
when SSAB is high.
SELZ/I
28
S
I
Select Zilog or Intel mode. SELZ/I is used to select between a Zilog-like or Intel-like
microcontroller. 1 = Zilog, 0 = Intel.
SIN
33
U
I
Serial data input. SIN moves information from the communication line or modem to the
TL16PC564B UART receiver circuits. Data on the serial bus is disabled when operating in the
loop mode.
SOUT
45
U
O
Serial out. SOUT is the composite serial data output to a connected communication device.
SOUT is set to the marking (logic 1) state as a result of a reset.
SSAB
3
S
I
Separate subsystem address bus. SSAB is used to select between a multiplexed address/data
bus subsystem interface (SSAB = 0) and a subsystem interface with separate address and data
buses (SSAB = 1). This signal has an internal pulldown resistor.
STSCHG
74
H
O
Status change. STSCHG is an optional active-low output signal used to alert the host that a
subsystem write to attribute memory has occurred. This signal has an open-drain output.
TESTOUT
70
M
O
This is a production test output.
UARTCLK
51
M
O
UART clock. UARTCLK is a clock output whose frequency is determined by the frequency on
XIN and the divisor value on the PGMCLK register.
VCC
10,21,22,36,
47,52,60,
72,86,97
M
3.3-V or 5-V supply voltage
VTEST
2
M
I
VTEST is an active-high production test input with an internal pulldown resistor. It can be left
open or tied to ground.
WE
89
H
I
Write enable. WE is an active-low input signal used for strobing attribute-memory write data into
the card. This signal has an internal pullup resistor
WR(R/W)
31
S
I
Write or read/write enable. WR(R/W) is the active-low write enable in the Intel mode and
read/write in the Zilog mode.
XIN
42
M
I
Crystal input. XIN is a clock input divided internally based on the PGMCLK register value, then
used as the primary UART clock input.
Host = H, Subsystem = S, UART = U, Miscellaneous = M
