2. Status change in the
SC
(Short Circuit) Status Register(05H).
The automatic power driver circuit continuously monitors the output
drivers signal to update the specific bit in
SCM
which indicates pres-
ence or absence of the transmit line side short circuit condition.
3. Status change in the
AIS
(Alarm Indication Signal) Status
Register(13H). The AIS detector monitors the received signal to up-
date the specific bit in
AIS
which indicates presence or absence of a
AIS condition.
Interrupt Enable
The IDT82V2058 provides a latched interrupt output (
INT
) and the
three kinds of interrupts are all reported by this pin. When the Interrupt
Mask register (
LOSM
,
SCM
and
AISM
) is set to ‘1’, the Interrupt Sta-
tus register (
LOSI, SCI
and
AISI
) is enabled respectively. Whenever
there is a transition (‘0’ to ‘1’ or ‘1’ to ‘0’) in the corresponding Status
register, the Interrupt Status register will change into ‘1’, which means
an interrupt occurs, and there will be a transition from high to low on
INT
. An external pull-up resistor of approximately 10k
is required to
support the wire-OR operation of
INT
. When any of the three Interrupt
Mask registers is set to ‘0’ (the power-on default value is ‘0’), the cor-
responding Interrupt Status register is disabled and the transition on
status register is ignored.
Interrupt Clearing
When an interrupt occurs, the Interrupt Status registers
(
LOSI, SCI
and
AISI
) are read to identify the interrupt source. And these registers
will be cleared to ‘0’ after the corresponding Status register (
LOS, SC
and
AIS
) being read. The Status registers will be cleared once the
corresponding conditions are met.
Pin
INT
is pulled High when there are no pending interrupt left.
The interrupt handling in the interrupt service routine is showed

ure-17.
