3.18.2.2.1 High-Performance Communications (FX ONLY)
If high-performance options are available for the selected device they will appear in the “Shift
Frequency in MHz” drop-down.
Cyclone
FX
programmers are capable of high-performance
communications when using certain ARM Cortex targets in SWD mode.
Note: Cyclone LC
programmers cannot currently take advantage of high-performance options, although
the frequencies appear in the display.

PORT C: 14-Pin Debug Connector (MPC55xx-57xx, SPC5, DSC, S32 (Power))
The Cyclone provides a standard 14-pin 0.100-inch pitch dual row 0.025-inch square header for
MPC55xx-57xx, DSC (MC56F8xxx), S32R, or STMicroelectronics’ SPC5 targets. The location of
the this header is indicated as PORT C in
