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 19.6.2, 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.

Bit10:

TST2

Bit9:

TST1

Bit8:

TST0

Description

Normal mode (initial value)

Listen-only mode (receive-only mode)

Self test mode 1 (external)

Self test mode 2 (internal)

Write error counter

Error passive mode

Setting prohibited

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.

Bit7: MCR7

Description

Auto-wake by CAN bus activity disabled (Initial value)

Auto-wake by CAN bus activity enabled
