FUNCTIONAL DESCRIPTION
FUNCTIONAL INTERNAL BLOCK DESCRIPTION
The IC and the MCU communicate using the SPI control
These 2 outputs notify the MCU when the IC is in reset
WATCHDOG TIMER
timeout function. The SPI control register provide the choice
as well as the timeout value. When the watchdog timer is not
properly serviced by the MCU, an error signal (WDOGN low)
and a reset signal (RSTN low) are output.
CAN INTERFACE/CONTROL
MCU through the use of SPI control register bits.
The timer can be used as a watchdog window or watchdog
The operation of the CAN interface is controlled by the
