12. Register definition
The following tables describe the register definition for the UCB1400. The UCB1400
shall follow the AC ’97 2.1 Interoperability Requirements and Recommendationsas
follows:
Non-implemented or reserved register bits: All reserved or non-implemented
register bits (marked ‘X’ in the tables) are required to return ‘0’ when read.
Non-implemented Addresses: Read access to non-implemented registers are
required to echo a ‘valid’ 7-bit register address in Input Slot 1 and return ‘valid’
0x0000 data in Input Slot 2 on the next AC-link frame.
Odd Register Addresses: Read (and write) access to odd register addresses are
required to be treated the same as non-implemented addresses, instead of
aliasing them to the next lower even-numbered register.
Codec register read data need to be returned in the next AC-link frame following
the frame in which the read request occurs.
Codec-Ready and audio DAC/ADC status bits shall only change from ‘ready’ to
‘not ready’ in response to a PR state change issued by the Controller to the
Power-down Control/Status registers 0x26. This guarantees that once data is
actively flowing on a slot, the Controller does not have to continuously read the
Power-down Control/Status register to detect any unexpected Codec PR status
change.
