• Description: Isdn Adapter Circuit Ipac
• Manufacturer: ETC-unknow

4.3.15
Value after reset: (not defined)
SAP2
SAPI2 ... SAPI2 value
Value of the second programmable Service Access Point Identifier (SAPI) according to
the ISDN LAPD-protocol.
MCS ... Modulo Count Select. Used in auto-mode only.
This bit determines the HDLC-control field format as follows:
0: One-byte control field (modulo 8)
1: Two-byte control field (modulo 128)
4.3.16
Value after reset: (not defined)
RSTAD
RDA ... Receive Data
A “1” indicates that data is available in the RFIFOD. After an RME-interrupt, a “0” in this
bit means that data is available in the internal registers RHCRD or SAPR only (e.g. S-
frame). See also RHCRD-register description table.
RDO ... Receive Data Overflow
If RDO=1, at least one byte of the frame has been lost, because it could not be stored in
RFIFOD.
CRC ... CRC Check
The CRC is correct (1) or incorrect (0).
RAB ... Receive Message Aborted
The receive message was aborted by the remote station (1), i.e. a sequence of seven
1’s was detected before a closing flag.
