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.
