When the slave sees
Bit 2
In the
OBCB
&
OBDCB
set, it knows it needs to resynchronize its
handshaking bits in the
IBCB
&
IBDCB.
So the Slave will acknowledge the resynchronization request by setting
Bit 2,
and will clear
Bit 1
and
Bit 0
in the
IBCB
&
IBDCB
.
Note that whatever values Bit 1 or Bit 0 had, they will be set to 0. This process forces the
handshaking into a known state.

Green
changes below)
