Comments:
• RWD: Restarts the watchdog counter
• EXT_TS: The bit select the mode of the input pin TS/ACT_OFF:
– EXT_TS = low (active off):
TS/ACT_OFF pin is used as input to switch the H-bridge in tristate and back.
Details are discribed in Section 3.12.1.
– EXT_TS = high (thermal sensor interface):
TS/ACT_OFF pin is used as thermal sensor interface for external temperature
diodes. Details are discribed in Section 3.12.2.
• EXTTH[5:0]: Determines the threshold of the external thermal shutdown/warning
