Evaluation Board Hardware Description
8. MTX - Provides the transmit data to the ISO9141 line
9. RESETB - When the RESETB line is held low, the MC33814 inhibits the internal watchdog reset.
These nine signals are provided by the nine parallel outputs from the USB/SPI interface as described
below:
1. O2HIN- Connected to the DATA4 signal
2. IGNIN1 - Connected to the DATA2 signal
3. IGNIN2 - Connected to the DATA3 signal
4. INJIN1 - Connected to the DATA0 signal
5. INJIN2 - Connected to the DATA1 signal
6. RIN1 - Connected to the CNTL1 signal
7. RIN2 - Connected to the CNTL0 signal
8. MTX - Connected to the CNTL2 signal
9. RESETB - Connected to the CNTL3 signal
The DATA0 -DATA4 and CNTL0-CNTL3 signals are logic level outputs from the USB/SPI dongle,
controllable directly from the SPIGen program. An example SPIGEN configuration file called
“KIT33814SW.spi” is provided in the software bundle which contains several batch file examples.
If the user prefers to supply the various MC33814 input signals externally, other than from the USB-SPI
Interface, the connections are available on the connector listed below.
