Temperature Sensor Interface - Analog Devices ADSP-BF609 EZ-KIT Lite Manual

Upon rotating to the left,
count decreases.
If the processor pins are needed on the expansion interface III, disconnect
the rotary encoder switch via SoftConfig. See
Switches (SoftConfig)
An example program is included in the EZ-KIT Lite installation directory
to demonstrate how to set up and access the rotary encoder.

Temperature Sensor Interface

Two external pins (
to an internal thermal diode. The EZ-KIT Lite uses ON Semiconductor
ADM1032 digital thermometer and under/over temperature alarm to
monitor the processor's temperature as well as the thermal diodes inside
the ADM1032 device. The thermometer uses the I
the processor. The following software-controlled signals are used for tem-
perature monitoring.
•
TEMP_IRQ_EN
•
TEMP_THERM_EN
The thermal limit flag is connected to an LED (
the temp exceeds the limit. The thermal limit flag and ADM1032 IRQ
connect to flag pins of the processor, but are nonessential for temperature
monitoring. Consequently, the software-controlled switches have these
signals disconnected from the ADSP-BF609 processor by default.
See Thermal Limit LED (LED5)
Config) for more information.
Example programs are included in the EZ-KIT Lite installation directory
to demonstrate temperature sensor operations.
