Control signal description:
P_OK
Active high signal from the power supply indicating that the 5V and 3V3 supplies are within
operating limits. It is strongly recommended to use an ATX supply with the 886LCD/ATX(GV)
and 886LCD/ATXU(GV) boards, in order to implement the supervision of the 5V and 3V3
supplies. These supplies are not supervised onboard the 886LCD/ATX(GV) and
886LCD/ATXU(GV) boards.
PS_ON#
Active low open drain signal from the board to the power supply to turn on the power supply
outputs. Signal must be pulled high by the power supply.
