28(+1) CHANNEL HIGH-DENSITY T1/E1/J1 LINE INTERFACE UNIT
Pin Description

IM
Input
(Pull-Up)
AF15
IM: Interface Mode Selection
In Parallel Motorola or Intel microprocessor interface, IM selects multiplexed bus or non-multi-
plexed bus for the device:
GNDD - Parallel Motorola /Intel Non-Multiplexed microprocessor interface.
Open - Parallel Motorola /Intel Multiplexed microprocessor interface.
In Serial microprocessor interface, this pin should be connected to GNDD.
ALE / AS
Input
AG15
ALE: Address Latch Enable
In Parallel Intel Multiplexed microprocessor interface, this multiplex pin is used as ALE.
The address on A[10:8] and D[7:0] (A[7:0] are ignored) is sampled into the device on the fall-
ing edges of ALE.
AS: Address Strobe
In Parallel Motorola Multiplexed microprocessor interface, this multiplex pin is used as AS.
The address on A[10:8] and D[7:0] (A[7:0] are ignored) is latched into the device on the falling
edges of AS.
In Parallel Motorola /Intel Non-Multiplexed microprocessor interface, this pin should be pulled
high.
In Serial microprocessor interface, this pin should be connected to GNDD.
SCLK / DS / RD
Input
AK17
SCLK: Shift Clock
In Serial microprocessor interface, this multiplex pin is used as SCLK.
SCLK inputs the shift clock for the Serial microprocessor interface. Data on SDI is sampled by
the device on the rising edge of SCLK. Data on SDO is updated on the falling edge of SCLK.
DS: Data Strobe (Active Low)
In Parallel Motorola microprocessor interface, this multiplex pin is used as DS.
During a write operation (R/W = 0), data on D[7:0] is sampled into the device. During a read
operation (R/W = 1), data is driven to D[7:0] by the device.
RD: Read Strobe (Active Low)
In Parallel Intel microprocessor interface, this multiplex pin is used as RD.
RD is asserted low by the microprocessor to initiate a read operation. Data is driven to D[7:0]
by the device during the read operation.
SDI / R/W / WR
Input
AH16
SDI: Serial Data Input
In Serial microprocessor interface, this multiplex pin is used as SDI.
Address and data on this pin are serially clocked into the device on the rising edge of SCLK.
R/W: Read / Write Select
In Parallel Motorola microprocessor interface, this multiplex pin is used as R/W.
R/W is asserted low for write operation or high for read operation.
WR: Write Strobe (Active Low)
In Parallel Intel microprocessor interface, this multiplex pin is used as WR.
WR is asserted low by the microprocessor to initiate a write operation. Data on D[7:0] is sam-
pled into the device during a write operation.
Name
I / O
Pin No.
