Activate bit timing parameters by
sending
the following message:
Item
Value
COB-ID
0x7E5
Length
3
Data 0
0x15
(cs=19 for activate bit timing parameters)
Data 1
<delay_lsb>
Data 2
<delay_msb>
The delay individually defines the duration of the two periods of time to wait until the bit
timing parameters switch is done (first period) and before transmitting any CAN message
with the new bit timing parameters after performing the switch (second period). The time
unit of switch delay is 1 ms.
