The GPIC responds with medium timing to master accesses. (i.e. DEVSELB is
asserted 2 PCICLK cycles after FRAMEB asserted). The GPIC inserts five wait
states on reads to the internal CBI register space (six wait states for the 2nd and
subsequent dwords of a burst read). The target machine will only terminate an
access with a Retry if the target is locked and another master tries to access the
GPIC. The GPIC will terminate any access to a non-burst area with a
Disconnect and always with data transferred. The target does not support
delayed transactions. The GPIC will perform a Target-Abort termination only in
the case of an address parity error in an address that the GPIC claims.
