4.3.13
Value after reset: (not defined)
SAPR
When transparent mode 1 is selected SAPR contains the value of the first address byte
of a receive frame.
4.3.14
Value after reset: (not defined)
SAP1
SAPI1 ... SAPI1 value
Value of the first programmable Service Access Point Identifier (SAPI) according to the
ISDN LAPD protocol.
CRI ... Command/Response Interpretation
CRI defines the end of the ISDN user-network interface the IPAC is used on, for the
correct identification of “Command” and “Response” frames. Depending on the value of
CRI the C/R-bit will be interpreted by the IPAC, when receiving frames in auto mode, as
follows:
For transmitting frames in auto mode, the C/R-bit manipulation will also be done
automatically, depending on the value of the CRI-bit (refer to XAD1 register description).
In message transfer modes with SAPI address recognition the first received address
byte is compared with the programmable values in SAP1, SAP2 and the fixed group
SAPI.
In 1-byte address mode, the CRI-bit is to be set to “0”.
