Mode, Osc Enable, Boot EEPROM Select, and Addr Select DIP Switch S2
DIP switch S2 is a multi-purpose selector switch (Figure 1-27 and Table 1-27, page 57).
FPGA Mode: S2 switches 3, 4, and 5 control the FPGA mode (Table 1-26).
Oscillator Enable: S2 switch 1, CCLK_EXTERNAL, controls the enable pin of the 47 MHz
oscillator SiT8102 (X4). When switch 1 is closed (CCLK_EXTERNAL High), X4 drives a
47 MHz clock onto the FPGA_CCLK signal.
Boot EEPROM Select: S2 switch 2 is used to select the between the Xilinx Platform Flash or
the Numonyx Linear BPI Flash for the FPGA boot memory device.
Upper or Lower Address Select: S2 switch 6 is used to select the upper or lower half of
flash memory U4 as the source of the FPGA bitstream image. When FLASH_A23 is High,
the upper half of the address is selected. When FLASH_A23 is Low, the lower half of the
address is selected.
Table 1-26 shows the FPGA configuration modes controlled by S2 switches 3, 4, and 5.
