When the power supply is in the "request power down" state, the power bits will be reset to 0=off after some time. | |||
== CFG9_SDMMCCTL == | |||
This register controls power of multiple ports/controllers and allows to map controller 3 to ARM9 or ARM11. The SD card can be accessed on ARM11 by setting bit 8 and clearing bit 9. | |||
