connects to DSTi1 of the PMAC and to the receive
side of the system. This allows the PMAC to perform
a payload loopback by internally connecting DSTi1 to
DSTo. In normal operation, transmit data will flow
from DSTi0 to DSTo of the PMAC to DSTi of the
MT8976/77.
PMAC RESET
The MT8926 functions may be suspended by making
the RESET input low (RESET must be high for
normal operation). In the reset state, data entering
the PMAC on FDLi, DSTi0 and CSTi0 will pass
through unaltered to FDLo, DSTo and CSTo
respectively. E8Ko will be high, IRQ will be high
impedance and the 1SEC output (and TMR bit) will
be low.
After the MT8976/77 has acquired frame synchroni-
zation and RESET returns high, the MT8926 will
require two superframes to acquire synchronization
and two ST-BUS frames to align to the ST-BUS.
RESET can be used to prevent DS1 interface
