PM Framework enables runtime control of power supplies using MIOs. These controls can be used to power up/down PL, FPD and LPD (whole chip). If the end application needs to realize power states that involve powering ON/OFF PL and FPD domains, then the board should be designed to connect the respective MIOs to power supply controller as described in the table below:
|

PMU GPO |

MIO 33 |
GPO1[1] |
PLD |
|
MIO 34 |
GPO1[2] |
Software defined, but in general used for full chip or board power down |
Note that these MIOs will be tri-stated during power up and booting. So, a strong pull-up should be provided on the board to keep the power ON as default state during startup.
