Chapter 12 Freescale’s Controller Area Network (S08MSCANV1)
If the WUPE bit in CANCLT0 is not asserted, the MSCAN will mask any activity it detects on CAN. The
RXCAN pin is therefore held internally in a recessive state. This locks the MSCAN in sleep mode
(Figure 12-45). WUPE must be set before entering sleep mode to take effect.
