Data Strobe/ Write Enable/Serial Data/Line Length Input
Intel Parallel Host Mode - This pin “WR” functions as a
write enable.
Motorola Parallel Host Mode - This pin “DS“ functions as
a data strobe input.
Serial Host Mode - This pin “SDI” functions as the serial
data input.
Hardware Mode - As LEN0, this pin controls the transmit
pulse shapes for both E1 and T1/J1 modes. This pin also
selects which mode is used E1 or T1/J1 (Refer to
on page
Read/Write/ Read Enable/Line Length Input
Intel Parallel Host Mode - This pin “RD” functions as a
read enable.
Motorola Parallel Host Mode - This pin “R/W” functions as
the read/write input signal.
Hardware Mode - As LEN1, this pin controls the transmit
pulse shapes for both E1 and T1/J1 modes. This pin also
selects which mode is used E1 or T1/J1 (Refer to
on page
Address Latch Enable/Serial Clock/Address Strobe/Line
Length Input
Intel Parallel Host Mode - This pin “ALE” functions as the
Address Latch Enable when configured for multiplexed ad-
dress/data operation.
Motorola Parallel Host Mode - This pin “AS” functions as
the active “low” address strobe when configured for multi-
plexed address/data operation.
Serial Host Mode - This pin “SCLK” is the serial clock
used for data I/O on SDI and SDO.
Hardware Mode - As LEN2, this pin controls the transmit
pulse shapes for both E1 and T1/J1 modes. This pin also
selects which mode is used E1 or T1/J1 (Refer to
on page
Chip Select Input/Jitter Attenuator Select
Host Mode - This active low input is used to enable ac-
cesses to the microprocessor interface in either serial or
parallel mode.
Hardware Mode - This pin controls the position of the Jitter
Attenuator.
