filter group in the mask bit mode can have two filters. Each filter contains a 16 bit identifier
register and a 16 bit mask register; In identifier list mode, all four registers are used as
identifier registers.
16 bit shielded bit mode
Identifier register n CAN_ FxR1[15:8] CAN_ FxR1[7:0]
Mask bit register n CAN_ FxR1[31:24] CAN_ FxR1[23:16]
Identifier register n+1 CAN_ FxR2[15:8] CAN_ FxR2[7:0]
Mask bit register n+1 CAN_ FxR2[31:24] CAN_ FxR2[23:16]

When a message can be filtered by multiple filters, the filter number stored in the receiving
mailbox determines which filter number to store according to the filter priority rules. The filter
priority rules are as follows:
● All 32-bit filters have higher priority than 16 bit filters
● For filters of the same width, the filter priority of identifier list is higher than that
of shielded bit mode
● Filters with the same width and mode have higher priority if they are numbered smaller
4.3.2. Custom baud rate
The user can set the user-defined baud rate through the upper computer, select time period
1, time period 2, and pre division coefficient, and calculate the baud rate according to the
calculation table provided.
