4.2.2.6 Configurable Interface Subchannel Register (CSCR)
Access in demultiplexed P-interface mode:
Access in multiplexed P-interface mode:
Reset value: 00
SC#1..#0 CFI Subchannel Control for logical port #.
Note: In CFI-mode 1:
bit 7
SC31
In CFI-mode 2:
In CFI-mode 3:
The subchannel control bits SC#1..SC#0 specify separately for each logical
port the bit positions to be exchanged with the data memory (DM) when a
connection with a channel bandwidth as defined by the CM-code has been
established:
