SD/MMC CONTROLLER
S5PC100 USER’S MANUAL (REV1.0)
8.12-10
Take the following steps to set Timeout:
(1) Check Command Inhibit (CMD) in the Present State register. Repeat this step until Command Inhibit (CMD) is
0. If Command Inhibit (CMD) is 1, the Host Driver does not issue a SD Command.
(2) If the Host Driver issues a SD Command with busy signal, go to step (3). If without busy signal, go to step (5).
(3) If the Host Driver issues an abort command, go to step (5). If no abort command is issued, go to step (4).
(4) Check Command Inhibit (DAT) in the Present State register. Repeat this step until Command Inhibit (DAT) is
0.
(5) Set the value corresponding to the issued command in the Argument register.
(6) Set the value corresponding to the issued command in the Command register.
NOTE:
If the upper byte is written in the Command register, it issues a SD command.
(7) Perform Command Complete Sequence
4.10
COMMAND COMPLETE SEQUENCE
The sequence for completing the SD Command is shown in Figure 8.12-10. The following errors might occur
during this sequence: Command Index/ End bit/ CRC/ Timeout Error.
(1) Wait for the Command Complete Interrupt. If the Command Complete Interrupt occurs, go to step (2).
(2) Write 1 to Command Complete (STACMDCMPLT) in the Normal Interrupt Status register to clear this bit.
(3) Read the Response register and get necessary information in accordance with the issued command.
(4) Judge whether the command uses the Transfer Complete Interrupt or not. If it uses Transfer Complete,
proceed with step (5). If not, go to step (7).
(5) Wait for the Transfer Complete Interrupt. If the Transfer Complete Interrupt occurs, go to step (6).
(6) Write 1 to Transfer Complete (STATRANCMPLT) in the Normal Interrupt Status register to clear this bit.
(7) Check for errors in Response Data. If there is no error, proceed with step (8). If there is an error, go to step
(9).
(8) Return Status of "No Error".
(9) Return Status of "Response Contents Error".
NOTES:
1. While waiting for the Transfer Complete interrupt, the Host Driver issues commands that do not
use the busy signal.
2. The Host Driver judges the Auto CMD12 (Stop Command) complete by monitoring Transfer
Complete.
3. If the last block of un-protected area is read using memory multiple blocks read command
(CMD18), OUT_OF_RANGE error may occur even if the sequence is correct. The Host Driver must
ignore it. This error appears in the response of Auto CMD12 or in the response of the next memory
command.
