NAME

mpcc − Multi protocol communications controller

SYNOPSIS

device mp0 at vba0 csr 0xff5000
thru
device mp15 at vba0 csr 0xff5f00

DESCRIPTION

The MPCC has three different connecter panel styles.  The 8 port MPCC will only support SYNC ports.  The 16 port MPCC will support any combination of SYNC or ASYNC ports.  The 32 port MPCC will only support ASYNC ports.  Each async line attached to the MPCC communications controller behaves as described in tty(7) and may be set to run at any of 16 speeds; see tty(7) for the encoding. 

Each MPCC controller uses 2 entries in the SCB for download/handshake, and command/response interrupts.  These entries start at 0xa0 for the 1st controllers download/handshake interrupts thru 0xaf, and 0xb0 for the 1st controllers command/response interrupts thru 0xbf.
