Register : resp1

Description

Response Register 1

Register Layout

Bits Access Reset Description
[31:0] R 0x0 ALT_SDMMC_RESP1_RESPONSE1

Field : response1

Register represents bit[63:32] of long response.

When CIU sends auto-stop command, then response is saved in register. Response for previous command sent by host is still preserved in Response 0 register. Additional auto-stop issued only for data transfer commands, and response type is always “short” for them.

Data Structure Documentation

struct ALT_SDMMC_RESP1_s

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.
