DDR memory module temp sensor, 1.7 V to 3.6 V
7
CTLB
Critical Trip Lock bit.
0 Critical Alarm Trip register is not locked and can be altered (default).
1 Critical Alarm Trip register settings cannot be altered.
This bit is initially cleared. When set, this bit will return a 1, and remains locked
until cleared by internal Power-on reset. This bit can be written with a single
write and do not require double writes.
6
AWLB
Alarm Window Lock bit.
0 Upper and Lower Alarm Trip registers are not locked and can be
altered (default).
1 Upper and Lower Alarm Trip registers setting cannot be altered.
This bit is initially cleared. When set, this bit will return a 1 and remains locked
until cleared by internal power-on reset. This bit can be written with a single
write and does not require double writes.
5
CEVNT
Clear EVENT
(write only).
0 No effect (default).
1 Clears active EVENT
in Interrupt mode. Writing to this register has no
effect in Comparator mode.
When read, this register always returns zero.
4
ESTAT
EVENT
Status (read only).
0 EVENT
output condition is not being asserted by this device (default).
1 EVENT
output pin is being asserted by this device due to Alarm
Window or Critical Trip condition.
The actual event causing the EVENT
can be determined from the Read
Temperature register. Interrupt Events can be cleared by writing to the
Clear EVENT
bit (CEVNT). Writing to this bit will have no effect.
3
EOCTL
EVENT
Output Control.
0 EVENT
output disabled (default).
1 EVENT
output enabled.
When either of the Critical Trip or Alarm Window lock bits is set, this bit cannot
be altered until unlocked.
2
CVO
Critical Event Only.
0 EVENT
output on Alarm or Critical temperature event (default)
1 EVENT
only if temperature is above the value in the critical
temperature register
When the Critical Trip or Alarm Window lock bit is set, this bit cannot be
altered until unlocked.
" Advisory note:
JEDEC specification requires only the Alarm Window lock bit to be set.
Work-around: Clear both Critical Trip and Alarm Window lock bits.
Future 1.7 V to 3.6 V SE98B will require only the Alarm Window lock
bit to be set.
