CHAPTER 3
IO-Map
see appendix A.
The addresses shown in this table for CAN registers are based on the settings for CS7 done in the Boot ROM.
CHAPTER 4
Interrupt Vector Table
see appendix B
.
CHAPTER 5
Power-on-sequence
All VDD pins should be connected to the same potential. The analogue supply voltage (AVCC) must not be turned
on before the digital supply voltage.
Immediately after power on always execute INIT at the INITX pin (input a low level to the INITX pin). Hold this low
level at the INITX pin long enough so that after release of the low level at INITX and the passing of the built in
waiting time stable oscillation of the oscillation circuit is achieved. INITX must be pulled low for at least 8 cycles of
the 4 MHz oscillation clock.
CHAPTER 6
Handling of Unused Input Pins
Leaving unused input pins open may result in misbehavior or latch up and possible permanent damage of the de-
vice. Therefore they must be tied to VDD or VSS through resistors. In this case those resistors should be more
than 2 KOhm.
Unused bidirectional pins should be set to the output state and can be left open, or the input state with the above
described connection.
The resistor of more than 2 KOhm is used to limit currents through the protection diodes. In case of voltages at the
unused pin of 0.3 V or more below VSS or 0.3 V or more above VDD currents which could cause latch-up will flow
through those diodes. It is possible to use one resistor to connect several pins to VDD or VSS. Care should be
taken not to connect pins from different supply voltage domains to one resistor.
