S5PC100 USER'S MANUAL (REV1.0)
Read Wait or stopping SD Clock. While stopping ADMA, any SD commands cannot be issued. (In case of Host
Controller version 1.00, the Stop At Block Gap Request can be set only when the card supports the Read Wait.)
Error occurrence during ADMA transfer may stops ADMA operation and generates ADMA Error Interrupt. The
ADMA Error State field in the ADMA Error Status register holds state of ADMA stopped. The host driver can
identify error descriptor location by following method. If ADMA stopped at ST_FDS state, the ADMA System
Address Register points the error descriptor line. If ADMA stopped at ST_TFR or ST_STOP state, the ADMA
System Address Register points the next location of error descriptor line. By this reason, ADMA2 shall not stop at
ST_CADR state.
