Table 72 Description of register bits
BIT SYMBOL
39 to 36 SPDO_BIT[39:36] reserved
35 to 33 SPDO_BIT[35:33] Word length. Value indicating the word length (see Table 73).
DESCRIPTION
32
SPDO_BIT[32]
Audio sample word length. Value to signal the maximum audio sample word length.
If bit 32 is logic 0, then the maximum length is 20 bits; if bit 32 is logic 1, then the
maximum length is 24 bits (see Table 73).
