Bit 7 — Auto-wake Mode (MCR7): MCR7 enables or disables the Auto-wake mode. If this bit is
set, the RCAN-ET automatically cancels the sleep mode (MCR5) by detecting CAN bus activity
(dominant bit). If MCR7 is cleared the RCAN-ET does not automatically cancel the sleep mode.
RCAN-ET cannot store the message that wakes it up.
Note: MCR7 cannot be modified while in sleep mode.

Bit 6 — Halt during Bus Off (MCR6): MCR6 enables or disables entering Halt mode
immediately when MCR1 is set during Bus Off. This bit can be modified only in Reset or Halt
mode. Please note that when Halt is entered in Bus Off the CAN engine is also recovering
immediately to Error Active mode.

Description

asserted.
