(18) CAN module time stamp register (C0TS)
The C0TS register is used to control the time stamp function.
After reset: 0000H
Note The TSEN bit is automatically cleared to 0.
Remark The lock function of the time stamp function must not be used when the CAN module

Time stamp lock function stopped.
The TSOUT signal is toggled each time the selected time stamp capture event occurs.
Time stamp lock function enabled.
The TSOUT signal is toggled each time the selected time stamp capture event occurs.
However, the TSOUT output signal is locked when a data frame has been correctly
received to message buffer 0
The time stamp capture event is SOF.
The time stamp capture event is the last bit of EOF.
