INDUSTRIAL TEMPERATURE RANGES
IDT82V2058 OCTAL E1 SHORT HAUL LINE INTERFACE UNIT
HOST INTERFACES
The host interface provides access to read and write the registers
in the device. The interface consists of serial host interface and
parallel host interface. By pulling pin MODE2 to VDDIO/2 or to High,
the device can be set to work in serial mode and in parallel mode
respectively.
Parallel Host Interface
The interface is compatible with Motorola or Intel host. Pins
MODE1 and MODE0 are used to select the operating mode of the
parallel host interface. When pin MODE1 is pulled to Low, the host
uses separate address bus and data bus. When High, multiplexed
address/data bus is used. When pin MODE0 is pulled to Low, the par-
allel host interface is configured for Motorola compatible hosts. When
High, for Intel compatible hosts. This is well described in the
Pin De-
scription
. The host interface pins in each operation mode is tabu-
lated in
Table-10.

Serial Host Interface
By pulling pin MODE2 to VDDIO/2, the device operates in the serial
host Mode. In this mode, the registers are accessible through a 16-bit
word which contains an 8-bit command/address byte (bit R/
W
and 5-ad-
dress-bit A1~A5, A6 and A7 are ignored) and a subsequent 8-bit data
byte (D0~D7). When bit R/
W
is 1, data is read out at pin SDO. When bit
R/
W
is 0, data is written into pin SDI to the register which is indicated by
address bits A5~A1.
INTERRUPT HANDLING
Interrupt Sources
There are three kinds of interrupt sources:
1. Status change in the
LOS
(Loss of Signal)
Status Register(04H).
The analog/digital loss of signal detector continuously monitors the re-
ceived signal to update the specific bit in
LOS
which indicates presence
or absence of a LOS condition.
