This bit can be modified only in reset mode.
Bit 14 — Auto Halt Bus Off (MCR14): If both this bit and MCR6 are set, MCR1 is
automatically set as soon as RCAN-ET enters BusOff.
Bit14 : MCR14

Description
RCAN-ET remains in BusOff for normal recovery sequence (128 x 11
Recessive Bits) (Initial value)
RCAN-ET moves directly into Halt Mode after it enters BusOff if MCR6 is
set.
This bit can be modified only in reset mode.
Bit 13 — Reserved. The written value should always be '0' and the returned value is '0'.
Bit 12 — Reserved. The written value should always be '0' and the returned value is '0'.
Bit 11 — Reserved. The written value should always be '0' and the returned value is '0'.
Bit 10 - 8 — Test Mode (TST[2:0]): This bit enables/disables the test modes. Please note that
before activating the Test Mode it is requested to move RCAN-ET into Halt mode or Reset mode.
This is to avoid that the transition to Test Mode could affect a transmission/reception in progress.
For details, please refer to section 17.4.1, Test Mode Settings.
Please note that the test modes are allowed only for diagnosis and tests and not when RCAN-ET is
used in normal operation.
