Reset output signal from watchdog circuit, active LOW/ power down control input. Mode selectable through
SM bus, power on is RESET# mode.(1) Byte 34 bit 5.
24/48MHz clock output, LOW 48MHz(2)
48MHz clock output. Phase is 180 different with 24_48, 48MHz1, and VCH. Output drive stength can
be doubled through SM programming.
GND
