Chapter 4: Configuration
SelectMAP Clock Selection
100
The default configuration of the ML555 board is to provide Master SelectMAP
configuration with the FPGA providing the configuration clock (CCLK) to both the FPGA
and Platform Flash devices. Slave SelectMAP configuration is not supported on the
ML555.
