voltage level applied to the HSWAPEN input pin in the FPGA configuration bank. If the
switch is in the OFF position, the weak preconfiguration I/O pull-up resistors are disabled.
If the switch is in the ON position, the weak preconfiguration I/O pull-up resistors are
enabled.

The JTAG chain supports bypassing of the CPLD or the Platform Flash devices. The FPGA
cannot be bypassed. Board connector/header P39 is used to enable or bypass the CPLD,
Notes:
1. Switch position 4 is used to select the DC voltage level applied to the HSWAPEN FPGA configuration
2. 0 = switch position is Closed or in the ON position. 1 = switch position is Open or in the OFF position.

SelectMAP, with a minimum 20 MHz configuration clock (CCLK) frequency, is the recommended
configuration method for PCI, PCI-X, and PCI Express applications utilizing the ML555 board.
