The procedure is as follows:
1. Write the
RCA should be written to the upper 16-bits of the
register.
2. Write the
command, configuring the command path state machine to expect
a short response by setting
response type is R1b.
3. Wait for the
register and clear the status bit once detected via the
register.
4. Ensure that the device is not busy and no errors occurred by
verifying the response contained in
5. Write the number of bytes to be transferred to the
register. For example, write 4096 to write eight blocks of 512
bytes.
6. Write the appropriate timeout value for a write operation to the
RSI_DATA_TIMER
7. Write the destination start address to the
The supplied address must be aligned to a 512-byte boundary if
misaligned accesses are not enabled and the card is not a
high-capacity SD card or a sector-addressable MMC card.
8. Write the
