High-speed CAN/LIN fail-safe system basis chip
The following operations are possible from Standby mode:
Cyclic wake-up by the watchdog via an interrupt signal to the microcontroller (the
microcontroller is triggered periodically and checked for the correct response)
Cyclic wake-up by the watchdog via a reset signal (a reset is performed periodically;
the SBC provides information about the reset source to allow different start
sequences after reset)
Wake-up by activity on the CAN-bus or LIN-bus via an interrupt signal to the
microcontroller
Wake-up by bus activity on the CAN-bus or LIN-bus via a reset signal
Wake-up by increasing the microcontroller supply current without a reset signal
(where a stable supply is needed for the microcontroller RAM contents to remain valid
and wake-up from an external application not connected to the SBC)
Wake-up by increasing the microcontroller supply current with a reset signal
Wake-up due to a falling edge at pin WAKE forcing an interrupt to the microcontroller
Wake-up due to a falling edge at pin WAKE forcing a reset signal
6.2.6
Sleep mode
In Sleep mode the microcontroller power supply (V1) and the INH/LIMP controlled
external supplies are switched off entirely, resulting in minimum system power
consumption. In this mode, the watchdog runs in time-out mode or is completely off.
Entering Sleep mode results in an immediate LOW level on pin RSTN, thus stopping any
operation of the microcontroller. The INH/LIMP output is floating in parallel and pin V1 is
disabled. Only pin SYSINH can remain active to support the V2 voltage supply; this
depends on the CAN programming. It is also possible for V3 to be on, off or in cyclic mode
to supply external wake-up switches.
If the watchdog is not disabled in software, it will continue to run and force a system reset
upon overflow of the programmed period time. The SBC enters Start-up mode and pin V1
becomes active again. This behavior can be used for a cyclic wake-up from Sleep mode.
Depending on the application, the following operations can be selected from Sleep mode:
Cyclic wake-up by the watchdog (only in time-out mode); a reset is performed
periodically, the SBC provides information about the reset source to allow different
start sequences after reset
Wake-up by activity on the CAN-bus, LIN-bus or falling edge at pin WAKE
An overload on V3, only if V3 is in a cyclic or in continuously on mode
6.2.7
Flash mode
Flash mode can only be entered from Start-up mode by entering a specific Flash mode
entry sequence. This fail-safe control sequence comprises three consecutive write
accesses to the Mode register, within the legal windows of the watchdog, using the
operating mode codes 111, 001 and 111 respectively. As a result of this sequence, the
SBC will enter Start-up mode and perform a system reset with the related reset source
information (RSS = 0110).
