• Bit 1—Halt Request (MCR1): Controls halting of the HCAN module.

Bit 1: MCR1

Description

Normal operating mode

(Initial value)

Halt mode transition request

• Bit 0—Reset Request (MCR0): Controls resetting of the HCAN module.

Bit 0: MCR0

Description

Normal operating mode (MCR0 = 0 and GSR3 = 0)

[Setting condition]

When 0 is written after an HCAN reset

Reset mode transition request

(Initial value)

In order for GSR3 to change from 1 to 0 after 0 is written to MCR0, time is required before the

HCAN is internally reset. There is consequently a delay before GSR3 is cleared to 0 after

MCR0 is cleared to 0.

15.2.2

General Status Register (GSR)

The general status register (GSR) is an 8-bit readable/writable register that indicates the status of

the CAN bus.

Bit:

—

GSR3

GSR2

GSR1

GSR0

Initial value:

R/W:

• Bits 7 to 4—Reserved: These bits always read 0. The write value should always be 0.

• Bit 3—Reset Status Bit (GSR3): Indicates whether the HCAN module is in the normal

operating state or the reset state. This bit cannot be modified.

Bit 3: MCR3

Description

Normal operating state

[Setting condition]

After an HCAN internal reset

Configuration mode

(Initial value)

[Reset condition]

MCR0-initiated reset state or sleep mode
