SOFTWARE ASPECTS
Introduction
This section describes the MC33989 operation and the microcontroller SPI software routine that has to be executed in order
to control the device. Structure of the Byte: ADR (3 bits) + R/W (1bit) + DATA (4 bits). MSB is sent first. Refer to MC33989
specifications for more details.
How to Enter in Normal Mode After a Power-Up
Figure 47. Normal Mode After Power-up
The DC current can be calculated as follows:
Idc= (Time in dominant * peak current of the fault) / total error frame time
Idc= (17+15)*peak current / ((23*15)+1408)=32 / 1753*peak current
Example for CANL2Vbat (peak current = - 240 mA): Idc = 32*(-) 240 / 1753=(-)4.38 mA
TX
RX
Rx is driven only during the glitch occuring on the CAN bus (the dominant time is shorter than a bit time)
TEC=128: the node reaches the error passive level
23 recessive bits: CAN passive error frame
Node sends one dominant bit. As there is still the fault, the TEC is incremented by 8 each time.
128 occurrences of 11 recessive bits
BUS OFF is recover
TEC reaches 255: the node is BUS OFF
