Description

The SDMMC_ACKTIMER register contains the acknowledgment timeout period, in SDMMC_CK bus clock periods. A counter loads the value from the SDMMC_ACKTIMER register, and starts decrementing when the data path state machine (DPSM) enters the Wait_Ack state. If the timer reaches 0 while the DPSM is in this states, the acknowledgment timeout status flag is set.

Fields

ACKTIME

Boot acknowledgment timeout period This bit can only be written by firmware when CPSM is disabled (CPSMEN = 0). Boot acknowledgment timeout period expressed in card bus clock periods.
