1 eMIOS timing specified at fSYS = 64 MHz, VDD12 = 1.14 V to 1.32 V, VDDE_x = 3.0 V to 5.5 V, TA = –40 to 105 °C, and
CL = 50 pF with SRC = 0b00.
2 There is no limitation on the peripheral for setting the minimum pulse width, the actual width is restricted by the pad delays.
Refer to the pad specification section for the details.
3 Parameter values guaranteed by design.
4.18.9 FlexCAN timing
The CAN functions are available as TX pins at normal I/O pads and as RX pins at the always on domain.
There is no filter for the wakeup dominant pulse. Any high-to-low edge can cause wakeup if configured.
