SE98A
DDR memory module temp sensor, 1.7 V to 3.6 V
7.3.2   EVENT
 thresholds
7.3.2.1   Alarm window
The device provides a comparison window with an UPPER trip point and a LOWER trip
point, programmed through the Upper Boundary Alarm Trip register (02h), and Lower
Boundary Alarm Trip register (03h). The Upper Boundary Alarm Trip register holds the
upper temperature trip point, while the Lower Boundary Alarm Trip register holds the lower
temperature trip point as modified by hysteresis as programmed in the Configuration
register. When enabled, the EVENT
 output triggers whenever entering or exiting (crossing
above or below) the alarm window.
" Advisory notification:
  NXP device: The EVENT
 output can be cleared through the Clear EVENT
 bit
(CEVNT) or SMBus ALERT.
  Competitor device: The EVENT
 output can be cleared only through the
Clear EVENT
 bit (CEVNT).
  Work-around: Only clear EVENT
 output using the Clear EVENT
 bit (CEVNT).
  There will be no change to the NXP device.
The Upper Boundary Alarm Trip should always be set above the Lower Boundary Alarm
Trip.
"  Advisory notification:
  NXP device: Requires one conversion cycle (125 ms) after setting the alarm 
window before comparing the alarm limit with temperature register to ensure that
there is correct data in the temperature register before comparing with the Alarm
Window and operating EVENT
 output.
  Competitor devices: Compares the alarm limit with temperature register at any 
time, so they get the EVENT
 output immediately when new UPPER or LOWER
Alarm Windows and the EVENT
output are set at the same time.
  Work-around: Wait at least 125 ms before enabling EVENT
 output (EOCTL = 1).
  SE98B will compare alarm window and temperature register immediately after 
setting.
