Register 42h: Interrupt Status Register 2
Note 8.10 This register is cleared on a read if no events are active.
This register is read only – a write to this register has no effect.
The Interrupt Status Register 2 bits is automatically set by the device whenever a remote temperature
sensor error occurs, a tach reading value is above the minimum value set in the tachometer minimum
registers, or whenever the 12V input voltage violates the limits set in the limit and parameter registers.
The Interrupt Status Register 2 register holds a set bit until the event is read by software or until the
individual interrupt enable bit is cleared.
This register holds a bit set until the event is read by software or until the individual enable bit is
cleared (see Note below). The contents of this register are cleared (set to 0) automatically by the
EMC6D103 after it is read by software, if the voltage no longer violate the limits set in the limit and
parameter registers, if the temperature sensor error no loner exists, or if the tach reading register is
no longer above the minimum. Once set, the Interrupt Status Register 2 bits remain set until a read
event occurs or until the individual interrupt enable bit is cleared, even if the voltage, Tach, or diode
event no longer exists.

The EMC6D103 automatically sets this bit to 1 when the 2.5V input
voltage is less than or equal to the limit set in the 2.5V Low Limit register
or greater than the limit set in the 2.5V High Limit register.
The EMC6D103 automatically sets this bit to 1 when the Vccp input
voltage is less than or equal to the limit set in the Vccp Low Limit register
or greater than the limit set in the Vccp High Limit register.
The EMC6D103 automatically sets this bit to 1 when the VCC input
voltage is less than or equal to the limit set in the VCC Low Limit register
or greater than the limit set in the VCC High Limit register.
The EMC6D103 automatically sets this bit to 1 when the 5V input voltage
is less than or equal to the limit set in the 5V Low Limit register or greater
than the limit set in the 5V High Limit register.
The EMC6D103 automatically sets this bit to 1 when the temperature
input measured by the Remote1- and Remote1+ is less than or equal to
the limit set in the Remote Diode 1 Low Temp register or greater than the
limit set in Remote Diode 1 High Temp register.
The EMC6D103 automatically sets this bit to 1 when the temperature
input measured by the internal temperature sensor is less than or equal
to the limit set in the Internal Low Temp register or greater than the limit
set in the Internal High Temp register.
The EMC6D103 automatically sets this bit to 1 when the temperature
input measured by the Remote2- and Remote2+ is less than or equal to
the limit set in the Remote Diode 2 Low Temp register or greater than the
limit set in the Remote Diode 1 High Temp register.
The device automatically sets this bit to 1 when a status bit is set in the
Interrupt Status Register 2.
