SW package basic
›TLE8080EM watchdog (WD) has been disabled on HW (with jumper)
›TLE8082ES window watchdog (WWD) is being serviced continuously via SPI
(mandatory for its channel(s) activation and to put device into AfterRun state
successfully)
›XMC setup: TLE8082ES Channel 1/2 default operation parameters are
–duty cycle: 50%
–Frequency: 10Hz
–The user can directly change the parameter in the Arduino code, if needed (see
variable declaration)
