Section 15 Controller Area Network (HCAN)
15.2.2
The general status register (GSR) is an 8-bit readable register that indicates the status of the CAN
bus.
Bits 7 to 4—Reserved: These bits always read 0.
Bit 3—Reset Status Bit (GSR3): Indicates whether the HCAN module is in the normal operating
state or the reset state. Writes are invalid.
Bit 3

Bit 2—Message Transmission Status Flag (GSR2): Flag that indicates whether the module is
currently in the message transmission period. The “message transmission period” is the period
from the start of message transmission (SOF) until the end of a 3-bit intermission interval after
EOF (End of Frame). Writes are invalid.
