2.8.4.3 fastPollingMode

The purpose of fastPollingMode is to continuously check all participating service/channel configurations for valid telegrams without any interruption. This mode is very similar to the PollingMode but there is no support of the self-check functionality and no sleep period is executed, as shown in the following figure. Fast polling is also known as “scanning”.
Figure 2-23. Fast Polling Cycle Definition

If the polling period is set to 0 ms in the confT1COR EEPROM setting, fastPollingMode is activated. During operation, fastPollingMode can be enabled by overwriting the confT1COR SRAM variable manually with 0x00 by using the “Write SRAM/Register” SPI command if the system is in IDLEMode. For more information, see Write SRAM/Register.

Note: EOP signals are ignored in this mode. Furthermore, VCO tuning on the initial service/channel configuration is not supported. For more information, see VCO Tuning.
