CPLD TurboLoader

A CPLD (Complex Programmable Logic Device) is a smaller version of an FPGA (described above) with permanent Flash storage built in. The Pico E-15 contains one CPLD that loads and reconfigures the FPGA. The Pico firmware guide describes how to access the CPLD TurboLoader.

The Flash ROM’s address bus can be controlled by either the TurboLoader or the FPGA (but not both). During power-up or reboot, the TurboLoader is in control of the Flash ROM Address bus. At all other times the FPGA is in control of the address bus.
