Thermo shutdown
The TS4975 device has internal protection in case of over temperature by thermal shutdown.
Thermal shutdown is active when the device reaches temperature 150°C.
When thermo shutdown protection is active, value $Fxh (1111xxxx binary) can be read from the
internal device registry.
When thermo shutdown protection state disappears, the last value of control register can be
read.
