0: When the SBC is in Normal mode (MC = 1x):
When the SBC is in Standby/Sleep mode (MC = 0x):
1: CAN is in Lowpower mode with bus wake-up detection enabled,
regardless of the SBC mode (MC = xx). CAN wake-up interrupts can be
requested.
0: The reset threshold is set to the 90 % V1 undervoltage detection voltage
(V
1: The reset threshold is set to the 70 % V1 undervoltage detection voltage

0: sampling continuously
1: sampling of WAKE1 is synchronized with WBIAS (sample rate controlled
by WBC)
CAN is in Active mode. The wake-up flag (visible on RXDC) is cleared
regardless of V2 output voltage.
CAN is in Off mode. Bus wake-up detection is disabled. CAN wake-up
interrupts cannot be requested.
