Firmware Revision Register (Read Only) - (Base + 200H)
This is a read only register. The ASCII code representing the current revision of
the MCS firmware file is readable from this location. For example, if the
firmware is at revision A then this register will read 0x41 in the least
significant byte or B= 0x42, C=0x43, etc.
HI-3111 MODES OF OPERATION
The HI-3111 CAN controller supports five modes of operation, namely,
Initialization Mode, Normal Mode, Loopback Mode, Monitor Mode and Sleep
Mode.
Initialization Mode
Initialization mode is used to configure the device before normal operation.
Initialization mode is the default mode following RESET and can also be
activated by programming the MODE<2:0> bits to <1xx> in the CTRL0 register.
Switching to Initialization mode resets the receiver and transmitter. During
initialization mode, the error counters are held reset.
Normal Mode
Normal mode is the standard operating mode of the HI-3111. In this mode,
the HI-3111 can transmit, receive and acknowledge messages from the CAN
bus, handling all aspects of the CAN protocol. Normal mode is activated by
programming the MODE<2:0> bits to <000> in the CTRL0 register.
Loopback Mode
Loopback mode is used for self-test. The transceiver digital input is fed back
to the receiver without being transmitted to the bus. Messages are
transmitted from the transmit FIFO in the usual way and received by the
receive FIFO as if they were received from a remote node on the bus.
