speed or 2x multiplexing.
Notes:
1. The I/O standards available will be different depending on the selected FPGA device family. Refer to the data sheet of the
appropriate FPGA device family for details. Also, different drive strength selections are available based on the selected I/O
standard.
Restrictions
A maximum of 15 ATC2 cores can be used in a single design.
