1…enables the control channel master.
Arbiter (receive channel selector) State:
000 : suspended
100 : full selection
011 : limited selection
001 : expect frame
010 : receive frame
Port Address.
The related frame was received on IOM-port PAD1…0
The related frame was received in IOM-channel CHAD2…0.
Suspend Counter Value.
The value (SCV7…0 + 1) × 32 defines the number of D-bits which are
analyzed in the state “expect frame” before the arbiter enters the state
suspended state and an interrupt is issued.
Min.: 32 × D-bits (16 frames), max: 8192 D-bits.
SCV6
AS1
available.
During reception of D-channel data from a channel which has been
enabled in the DCE0-3 registers all other enabled channels are sent the
“blocked” information from the Control Memory (CM).
