User’s Manual for Advantech
CPLD
•System memory assignments
•I/O control
•RTC control
Base on Advantech policy, Advantech won’t release the CPLD code to user. In fact, when user designs their own target carrier board, they don’t need to know the CPLD code. Advantech will release memory map of available memory block and available GPIOs. These are fully enough to users to develop their own carrier board.
