Description
Time-Out Response Error—Indicates that a
command response is not received in the time
specified in the RES_TO register. This can be
caused by:
• An unsupported command received at the
card(s)
• Another MMC/SD_OP_COND command
submitted after all cards have sent their voltage
ranges and the power-up routine is finished
• An identification command issued when all
cards are already in standby state
• No card is on the bus
Note: TIME_OUT_RESP is cleared only by an
internal status change or by removing the source
of the error.
Time-Out Read Data Error—Indicates that the
expected data from the card is not received in the
time specified in the READ_TO register.
TIME_OUT_READ is cleared only by an internal
status change or by removing the source of the
error.
