ZSSC3240 Cyclic Mode and Sequencer Operation Manual Evaluation Board Jumpers Setup Remove all jumpers and ensure that J21, J22 (SPI side), J12 (5V side) are in place as per Figure 1. Figure 1. EVB Jumper Settings Overall System Assembly Connect the Communication Board to the ZSSC3240EVB through the dedicated connector, and attach the Communication Board to the host PC via a USB cable (see Figure 2). -
Page 5: Cyclic Mode
Setup ZSSC3240 powers up in Cyclic Mode if the Default Mode dropdown is set to Cyclic Mode on the NVM tab of the Main page of the GUI, see Figure 3. -
Page 6: Exit
Figure 4. Cyclic Mode at Start Up Exit In Cyclic Mode the IC status is Busy, signifying that the ZSSC3240 is continuously measuring and converting the sensed signals. To exit Cyclic Mode click the ‘Start Command Mode’ button (see Figure 5) and enter the next user command. -
Page 7: Measurement Time Slot
A measurement time slot denotes the time needed to complete a predefined set of measurements and update the ZSSC3240 output. Pauses between the slots must be defined by the update period (CYC_period). The first slot in a predefined sequence is defined as slot 0. -

Page 9: Scheduler Operation
ZSSC3240 Cyclic Mode and Sequencer Operation Manual 5. Scheduler Operation The scheduler operation can be analyzed by probing the EOC signal. In the scope plots displayed in section 5 and 6, the channel CH1 is monitoring the EOC pin. The channel CH2 is generally used to monitor the AOUT pin and the analog output presence (Sensor or Temperature) with no specific goal of relating it with the input signal. -

Figure 19. Summary of Measured EOC Timings Sensor Connection Check The diagnostic checks available in the ZSSC3240 are one component of the tasks that can be included by the scheduler, in addition to the sensor and temperature measurements. “Cyclic Operation Sequence 1 / 2” part of the GUI settings are dedicated to show these measurements, see Figure 20. -
Page 14: Update Rate
ZSSC3240 Cyclic Mode and Sequencer Operation Manual Update Rate The scheduler allows the introduction of a selectable delay between the measurement slots, as shown in Figure Figure 21. Update Rate Setting The selection of 1ms delay in a AZSM+SM+AZTM+TM sequence with 1 slot pause for the temperature measurement is shown in Figure 22. -
