3.14.2 SDIO-IRQ and ReadWait Service Handling
In SDIO, there is a 1-bit or 4-bit interrupt response from the SDIO peripheral card. In 1-bit mode, the
interrupt response is simply that the SD_DAT[1] line is held low. The SD_DAT[1] line is not used as data
in this mode. The memory controller generates an interrupt according to this low and the system interrupt
continues until the source is removed (SD_DAT[1] returns to its high level).
In 4-bit mode, the interrupt is less simple. The interrupt triggers at a particular period called the "Interrupt
Period" during the data access, and the controller must sample SD_DAT[1] during this short period to
determine the IRQ status of the attached card. The interrupt period only happens at the boundary of each
block (512 bytes).
Figure 48. SDIO IRQ Timing Diagram
ReadWait is another feature in SDIO that allows the user to submit commands during the data transfer. In
this mode, the block temporarily pauses the data transfer operation counter and related status, yet keeps the
clock running, and allows the user to submit commands as normal. After all commands are submitted, the
user can switch back to the data transfer operation and all counter and status values are resumed as access
continues.
