DESCRIPTION
Logic 1 enables startup of measurement loop, logic 0 places the DS1780 in standby mode.
Caution: The INT output pin will not be cleared if the user writes a 0 to this location after an
0
START
R/W
interrupt has occurred (see “ INT Clear” bit). At startup, limit checking functions and
scanning begins. Note, all HIGH and LOW LIMITS should be set into the DS1780 prior to
turning on this bit. (Power-up default=0).

Logic 1 enables the INT output. 1=Enabled 0=Disabled (Power-up Default = 0)
Power-up Default = 0.
During Interrupt Service Routine (ISR) this bit asserted logic 1 clears INT output without
affecting the contents of the Interrupt Status Registers. The device will stop monitoring. It
will resume upon clearing of this bit. (Power-up default=1.)

R/W
Creates a RESET (Active Low) signal for 20 ms (min) on the RST output. (Power-up
default = 0) This bit is cleared once the RST pulse goes active.
Power-up Default = 0.
Logic 1 resets the chassis intrusion pin. (Power-up default = 0) This bit is cleared after CHS
becomes cleared.
Logic 1 restores power-up default values to all DS1780 registers except for the analog

Initialization

output and value RAM, which remain unchanged. This bit automatically clears itself since
the power on default is 0.
