ZGATE_filtering_on
Function Prototype
INT16 ZGATE_filtering_on(void);
Parameters
None.
Return Value
TRUE Static and SPI filtering are enabled.
FALSE Static and SPI filtering is disabled.
Description
This function is used to determine if static and SPI filtering are currently active. If ZGATE
successfully initializes, static and SPI filtering will be enabled. It is not possible to disable
these filtering mechanisms after ZGATE successfully initializes. The
zg_rules.usr ,
zg_rules.def and ZGATE_Conf.c files can be used to selectively disable static filter-
ing based on individual filtering criteria.
