Each channel has its own temperature sensor. If the temperature at the channel exceeds the thermal shutdown
temperature
to reactivate the channel, the temperature at the output must drop by at least the thermal hysteresis
over temperature latch must be cleared by SPI command HWCR.CL = 1
register OUT is still set, the channel will be turned on immediately (or according to the automatic PWM generator
setting) after the command HWCR.CL = 1

Additionally, each channel has its own dynamic temperature sensor. The dynamic temperature sensor improves
short circuit robustness by limiting sudden increases in the junction temperature. The dynamic temperature sensor
turns off the channel if its sudden temperature increase exceeds the dynamic temperature sensor threshold
channel turns off and latches. The retry latch is cleared by SPI command HWCR.CL = 1
bit in the SPI register OUT is still set, the channel will be turned on immediately (or according to the automatic PWM
generator setting) after the command HWCR.CL = 1
reactivations will be reset by every low to high transition on the input pin or the bit in SPI register OUT.
