TOD_TRIG_3[3]
R/W
0
Select TOD of DPLL 3 to be triggered by this GPIO.
The TOD read/write operation is triggered on the rising edge of this GPIO. The
tod_write_selection or tod_read_trigger for TOD 3 has to be equal to 'Selected
GPIO'.
CAUTION: if more than one GPIO is used to trigger the same TOD, the
behaviour is undefined.
