Description
Response time-out value. Value is in number of card
output clocks - cclk_out.
Value for card Data Read time-out; same value also
used for Data Starvation by Host time-out. Value is in
number of card output clocks - cclk_out of selected card.
Starvation by Host time-out. Value is in number of card
output clocks - cclk_out of selected card.
Description
MMC card clock supported. 0 - Non-low-power mode 1 -
Low-power mode; stop clock when card in IDLE (should
be normally set to only MMC and SD memory cards; for
SDIO cards, if interrupts must be detected, clock should
not be stopped). In MMC-Ver3.3-only mode, since there is
only one cclk_out, only cclk_low_power[0] is used.
supported. 0 - Clock disabled 1 - Clock enabled In
MMC-Ver3.3-only mode, since there is only one cclk_out,
only cclk_enable[0] is used.
Clock-enable control for up to 16 SD card clocks and one
MMC card clock supported.
