Data Sheet
CRAM Status Register (CSR)
Value after reset: 00
CCR
DCA
Read-back of the programmed value
BSYB
0: Momentary there is no transfer of CRAM data to the temporary area running. CRAM
1: Transfer of the CRAM block <CBADR> is running. CRAM access via microcontroller
CBADR
Read-back of the programmed value
CRAM Control Register (CCR)
Value after reset: 00
CCR
DCA
0: The normal CRAM area (80
1: The temporary CRAM area (coefficient block with 8 bytes corresponding to the
SBP
0: No back-up is initiated
1: A transition to SBP = ’1’ starts the back-up of the CRAM block <CBADR> into the
CBADR
Address of a coefficient block with 8 bytes corresponding to the COP_x sequences
(x=0...F) of the codec programming sequences
access via microcontroller interface is possible
interface is not allowed
COP_x sequences) is accessed by the codec DSP. The switching to the temporary
CRAM block happens as soon as the transfer of the block has completed (BSYB = ’0’)
