SD/MMC CONTROLLER
8.12-3
4 SEQUENCE
This section defines basic sequence flow chart divided into several sub sequences. "Wait for interrupts" is used in
the flow chart. This means the Host Driver waits until specified interrupts are asserted. If already asserted, then
follow the next step in the flow chart. Timeout checking required to detect no interrupt generated. This is not
described in the flow chart.
4.1 SD CARD DETECTION SEQUENCE
Figure 8.12-2 SD Card Detect Sequence
The flow chart to detect a SD card is shown in Figure 8.12-2. The steps shown in flowchart are explained below:
1. To enable interrupt for card detection, write 1 to the following bits:
Card Insertion Status Enable (ENSTACARDNS) in the Normal Interrupt Status Enable register
Card Insertion Signal Enable (ENSIGCARDNS) in the Normal Interrupt Signal Enable register
Card Removal Status Enable (ENSTACARDREM) in the Normal Interrupt Status Enable register
Card Removal Signal Enable (ENSIGCARDREM) in the Normal Interrupt Signal Enable register
2. If Host Driver detects the card insertion or removal, it clears the interrupt statuses. If Card Insertion interrupt
(STACARDINS) is generated, write 1 to Card Insertion in the Normal Interrupt Status register. If Card
Removal interrupt (STACARDREM) is generated, write 1 to Card Removal in the Normal Interrupt Status
register.
3. Check Card Inserted in the Present State register. If Card Inserted (INSCARD) is 1, the Host Driver supplies
power and clock to the SD card. If Card Inserted is 0, the other executing process of the Host Driver is closed.
