25.3.3
HACCSDR is a 32-bit read/write data register used for accessing the codec register. Write the
command data to HACCSDR and set the ST bit in the HACCR register to 1. The HAC then
transmits the data to the codec via slot 2.
After the codec has responded to a read request (HACRSR.STDRY = 1), the status data received
via slot 2 can be read out from HACCSDR. In both read and write, HACCSAR stores the related
codec register address.
