12.5.17.2 Acceptance Filter Enable Register
Each defined Acceptance Filter is enabled or disabled by a certain bit located within the Acceptance Filter Enable
Register. This allows to change the Acceptance Filter Contents “on the fly” during normal operation if the corresponding
filter is disabled previously. A disabled Acceptance Filter does not allow passing of messages to the receive buffer. If all
Acceptance Filters are disabled (default after hardware reset) no messages will pass to the receive buffer at all.
Table 33 Acceptance Filter Enable Register (ACF Enable) (CAN address 30)
Table 34 Acceptance Filter Enable Register (ACF Enable)
Note, if the Single Filter Mode is selected for an Acceptance Filter Bank, this single filter is related to the corresponding
Filter 1 Enable Bit. The Filter 2 Enable Bits have no influence within Single Filter Mode.
