NE1617A
Temperature monitor for microprocessor systems
the Alert Response byte from the Alert Response Address, which is a special slave
address to the SMBus. The ALERT
output cannot be reset by reading the device status
register.
The device was designed to accommodate the Alert interrupt detection capability of the
SMBus.
1
Basically, the SMBus provides Alert response interrupt pointers in order to
identify the slave device which has caused the Alert interrupt. The 7-bit Alert response
slave address is 0001 100 and the Alert response byte reflects the slave address of the
device which has caused Alert interrupt. Bit assignments of the Alert response byte are
listed in Table 9
. The ALERT output will be reset to HIGH state upon reading the Alert
response slave address unless the fault condition persists.
8.4 Power-up default condition
Upon power-up reset (power is switched off-on), the NE1617A goes into this default
condition:
" Interrupt latch is cleared, the ALERT
output is pulled HIGH by the external pull-up
resistor.
" The auto-conversion rate is at 0.25 Hz; conversion rate data is 02h.
" Temperature limits for both channels are +127 ?/SPAN>C for high limit, and -55 ?/SPAN>C for low
limit.
" Command pointer register is set to 00 for quickly reading the RIT.
8.5 Fault detection
The NE1617A has a fault detector to the diode connection. The connection is checked
when a conversion is initiated and the proper flags are set if the fault condition has
occurred.
1. The NE1617A implements the collision arbitration function per System Management Bus Specification Revision 1.1, dated
December 11, 1998, which conforms to standard I
2
C-bus arbitration as described in NXP document UM10204, I
