R
Parallel Cable IV Interface
The Parallel Cable IV (PC IV) download cable can also be used to program the XC2VP30.
The pinout provided in Figure 2-7 is compatible with the PC IV JTAG programming
solution.
Figure 2-7 shows the pinout of the PC IV JTAG connector.
System ACE JTAG Configuration Interface
The JTAG Configuration port on the System ACE device is connected directly to the JTAG
interface of the XC2VP30 device.Table 2-5 shows the JTAG connections from System ACE
to the XC2VP30.
GPIO LEDs and LCD
GPIO
The ML310 Hardware Platform provides direct GPIO access to eight LEDs for general
purpose use and provides indirect access to a 16 pin connector (J13) used to interface the
ML310 with a 2 Line by 16 character LCD Display, AND491GST. Access to the GPIO lines
is handled by a simple register interface that is connected XC2VP30 GPIO signals.
Figure 2-8 shows the connectivity of the ML310 LEDs and LCD.
The user also has an indirect access path to more GPIO capability via PCI Bus accesses
when controlling the GPIO header (J5) connected to the ALi M1535D+ South Bridge.
Please refer to section “ALi South Bridge Interface, M1535D+, U15” for more details on
programming and controlling the ALi M1535D+ GPIO port.
