Field : response_timeout | |
Response timeout value. Value is in number of card output clocks cclk_out. Field Access Macros: | |
#define | ALT_SDMMC_TMOUT_RESPONSE_TMO_LSB 0 |
#define | ALT_SDMMC_TMOUT_RESPONSE_TMO_MSB 7 |

#define | ALT_SDMMC_TMOUT_RESPONSE_TMO_SET(value) (((value) << 0) & 0x000000ff) |
Field : data_timeout | |
Value for card Data Read Timeout; same value also used for Data Starvation by Host timeout. The timeout counter is started only after the card clock is stopped.Value is in number of card output clocks cclk_out of selected card. Note: The software timer should be used if the timeout value is in the order of 100 ms. In this case, read data timeout interrupt needs to be disabled. Field Access Macros: | |

WARNING: The C register and register group struct declarations are provided for convenience and illustrative purposes. They should, however, be used with caution as the C language standard provides no guarantees about the alignment or atomicity of device memory accesses. The recommended practice for writing hardware drivers is to use the SoCAL access macros and alt_read_word() and alt_write_word() functions.
