PXAMMC(4) OpenBSD Programmer's Manual (Zaurus) PXAMMC(4)NAME
pxammc - MMC/SD/SDIO controller
SYNOPSIS
pxammc0 at pxaip?
sdmmc* at pxammc?
DESCRIPTION
The pxammc driver supports the MMC/SD/SDIO controller integrated in
PXA255 and PXA27x processors.
The sdmmc(4) subsystem performs SD/MMC transactions to communicate with
whatever MMC/SD/SDIO devices are inserted into the card slot.
SEE ALSOintro(4), sdmmc(4)HISTORY
The pxammc driver first appeared in OpenBSD 4.2.
AUTHORS
The pxammc driver was written by Uwe Stuehler <uwe@openbsd.org>.
CAVEATS
To work around a problem stated in an errata for the PXA27x processor
family, the driver limits the bus frequency to 9.75 MHz instead of the
theoretically supported maximum frequency of 19.5 MHz.
