SDHC_PROCTL field descriptions
Description
This read-only field is reserved and always has the value zero.
Wakeup Event Enable On SD Card Removal
This bit enables a wakeup event, via IRQSTAT[CRM]. FN_WUS (Wake Up Support) in CIS does not
effect this bit. When this bit is set, the IRQSTAT[CRM] and the SDHC interrupt can be asserted without
SD_CLK toggling. When the wakeup feature is not enabled, the SD_CLK must be active in order to assert
the IRQSTAT[CRM] and the SDHC interrupt.
0b Disabled
1b Enabled
Wakeup Event Enable On SD Card Insertion
This bit enables a wakeup event, via IRQSTAT[CINS]. FN_WUS (Wake Up Support) in CIS does not
effect this bit. When this bit is set, the IRQSTATEN[CINSEN] and the SDHC interrupt can be asserted
without SD_CLK toggling. When the wakeup feature is not enabled, the SD_CLK must be active in order
to assert the IRQSTATEN[CINSEN] and the SDHC interrupt.
0b Disabled
1b Enabled
Wakeup Event Enable On Card Interrupt
This bit enables a wakeup event, via IRQSTAT[CINT]. This bit can be set to 1 if FN_WUS (Wake Up
Support) in CIS is set to 1. When this bit is set, the card interrupt status and the SDHC interrupt can be
asserted without SD_CLK toggling. When the wakeup feature is not enabled, the SD_CLK must be active
in order to assert the card interrupt status and the SDHC interrupt.
0b Disabled
1b Enabled
This read-only field is reserved and always has the value zero.
