5.11.6 BCSR5 and BCSR7 Board Control—Status Register 3
and 5
BCSR5 to BCSR7 are additional control / status registers which may be accessed as a word
at offset 0x14 to 0x1C from BCSR base address. These registers are not implemented.
They may be read or written but with no valid data nor any effect on the board. The

5.12 COP/JTAG Port
The COP - Control Observation Port, is part of the PowerQUICC II’s JTAG machine,
implemented as a set of additional instructions and logic within the JTAG permissions. This
port may be connected to a dedicated debug station 1 , for extensive system debug.
There are several third party debug solutions on the market. These debug-stations may be
connected to the host computer via either Ethernet, Parallel-Port, RS232 or any other
media.
The debug station connection scheme is shown in Figure 5-10.
