The 16V(F16V) from the P board via pin1-4 of connector A02 is applied to the Power ICs
(Voltage regulators) on the A board to generate the SUB-Voltages used for signal processing
operation.
: SUB1.0V, 1.8V, 3.3V, and 5V
Each voltage regulators start up by high state of DCDCEN signal which is pull up to F16V.
So F16V is provided to A board, each SUB-voltage regulator ICs start output.
< : A board (SUB voltage) >
