Controller Area Network (CAN) Timing
1. If Wakeup glitch filter is enabled during the design initialization and also CAN is put into SLEEP mode then, any bus event
(on MSCAN_RX pin) whose duration is less than 5 micro seconds is filtered away. However, a valid CAN bus wakeup detec-
tion takes place for a wakeup pulse equal to or greater than 5 microseconds. The value of 5 microseconds originates from the
fact that the CAN wakeup message consists of 5 dominant bits at the highest possible baud rate of 1Mbps.
2. Parameters listed are guaranteed by design.
