3.7.4.3 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 (see the following figure). Fast polling is also known as scanning.
Figure 3-15. 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. See Write SRAM/Register from Related Links.

Note: EOP signals are ignored in this mode. Furthermore, VCO tuning on the initial service/channel configuration is not supported. See VCO Tuning from Related Links.
