56F803 Technical Data
3.13 Controller Area Network (CAN) Timing
Operating Conditions:
MSCAN_RX
CAN receive
Baud Rate
Bus Wakeup detection
1.
bus event (on MSCAN_RX pin) whose duration is less than 5 micro seconds is filtered away. However, a valid CAN bus
wakeup detection 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.
data pin
(Input)
If Wakeup glitch filter is enabled during the design initialization and also CAN is put into SLEEP mode then, any
Parameters listed are guaranteed by design.
