Page 5: Demonstration Set-Up
The purpose of this MRST dip switch is to allow easy interfacing of an external MCU to the HI-3110 such that the SPI signals from the Freescale MCU will be forced into high impedance so as not to conflict with an external MCU. For normal operation keep this switch open and use the RESET button to reset the MCU during testing. - Page 6 If the data doesn’t match the expected value from the previous transmission it will turn on the Red LED8 and halt. Transmitter Modes: If OPT1 is in the open position a 400us delay will be inserted between each transmission. Holt Integrated Circuits Arrow.com. Arrow.com. Arrow.com.
- Page 7 Sleep Mode status Serial Commands Menu A simple menu of commands is provided for resetting the HI-3110, reading and displaying the HI-3110 status registers, and a demo how to pass input strings to the program. There are provisions for additional user code to be implemented so custom commands can be developed and easily integrated.

Using the HI-3110 with an external MCU or FPGA To use the HI-3110 with an external MCU or FPGA close the RESET DIP switch 4 in SW2. This will hold the Freescale MCU in the reset state and keep the SPI signals from the Freescale MCU in tri-state. This allows the SPI signals to be driven by an external source without having to remove the Freescale MCU on the board. - Page 9 LED1-4 will reflect the lower nibble of byte3 of the data-field. CAN Error Detection While receiving frames if there are any errors detected in the HI-3110 registers, TEC, REC or ERR, they will be automatically logged on the Serial Port.
- Page 10 Normal Mode Resumed from Monitor Mode REC: 01 ERR: 04 The last line shows a BUS error that was caused when the HI-3110 was in Sleep Mode and woke up due to a CAN message coming in. Holt Integrated Circuits Arrow.com.
- Page 11 Monitor mode is a simple version similar to Receive mode but just captures the CAN data without providing an acknowledge bit on the Bus. Press Button-1 to stop receiving CAN messages and print the last 64 CAN frames and the HI-3110 status registers on the serial console.
- Page 12 This is very similar to normal Receive mode-2 but without Sleep Mode. The main purpose is to demonstrate how to use interrupts to received the CAN Bus data in the background. Press Button-1 to stop receiving CAN messages and print the last 64 CAN frames and the HI-3110 status registers on the serial console.

- Page 20 AN-175 HI-3110 Interrupts The HI-3110 can be configured to output status on the INT, STAT, GP1 and GP2 pins which connect to the MCU PP0 – PP3 inputs. Interrupt handlers are provided for the GP1 and GP1 for servicing TXCPLT and RXFIFO respectively on the PP3 and PP2 pins which are enabled by calling PortP_Int().
- Page 21 Al l the other functions in this module are based on and utilize these basic functions. Init3110() This function is provided to initialize the HI-3110 for the desired mode and bit rate. uint8 Init3110(const mode, uint8 ttdiv, uint8 wakeup, uint8 reset, uint8 bor) See the 3110Driver.h header file for the options available in the define statements.

Page 22: Transmit Mode
Select transmit mode from the SW1 dip switches and Press Button-1 after a POR to start transmitting frames. The transmit function configures the HI-3110 for normal mode at the CAN Bus rate according to the Bit Rate dip switches. A frame is composed of a predefined header “T8Header[]” and eight bytes for the data-field. - Page 23 All other messages other than 0x47 will be except by filter-3. Refer to the datasheet page 38 and example code for the bit assignments of the other 5 bytes in these arrays. Holt Integrated Circuits Arrow.com. Arrow.com.
