* @brief Extract up to 32 sequential bits from an array of 32-bit words
|
|
*
|
|
* Bits within the word are numbered in the increasing order from LSB to MSB.
|
|
*
|
|
* As an example, consider 2 32-bit words:
|
|
*
|
|
* 0x01234567 0x89abcdef
|
|
*
|
|
* On a little-endian system, the bytes are stored in memory as follows:
|
|
*
|
|
* 67 45 23 01 ef cd ab 89
|
|
*
|
|
* MMC_RSP_BITS will extact bits as follows:
|
|
*
|
|
* start=0 len=4 -> result=0x00000007
|
|
* start=0 len=12 -> result=0x00000567
|
|
* start=28 len=8 -> result=0x000000f0
|
|
* start=59 len=5 -> result=0x00000011
|
|
*
|
|
* @param src array of words to extract bits from
|
|
* @param start index of the first bit to extract
|
|
* @param len number of bits to extract, 1 to 32
|
|
* @return 32-bit word where requested bits start from LSB
