3.18.2.2.1 High-Performance Communications
If high-performance options are available for the selected device they will appear in the “Shift
Frequency in M Hz” drop-down. CYCLONE FX programmers are capable of high-performance
communications when using certain ARM Cortex targets in SWD mode.

3.18.3 PORT C: 20-Pin Debug Connector (Kinetis, S32 (ARM), other PEmicro-Supported ARM
devices)
3.18.3.1 JTAG Mode Pin Assignments
The Cyclone provides a 20-pin 0.100-inch pitch double row connector for ARM targets. The
location of the this header is indicated as PORT C under Part# CYCLONE_ACP_FX in Figure 3-5.
The 20-pin standard connector pin definitions for JTAG mode are as follows:
20-Pin Standard Connector JTAG Mode Pin Assignments
PIN 1 - TVCC NC* - PIN 2
PIN 3 - TRST or NC GND - PIN 4
PIN 5 - TDI GND - PIN 6
PIN 7 - TMS GND - PIN 8
PIN 9 - TCK GND - PIN 10
PIN 11 - NC* GND - PIN 12
PIN 13 - TDO GND - PIN 14
PIN 15 - RESET GND - PIN 16
PIN 17 - NC* GND - PIN 18
PIN 19 - NC* GND - PIN 20
Note: *The pin is reserved for internal use within the PEmicro interface.
3.18.3.2 SWD Mode Pin Assignments
CYCLONE FX programmers also support SWD Mode. This replaces the JTAG connection with a
clock and single bi-directional data pin.
20-Pin Standard Connector SWD Mode Pin Assignments
PIN 1 - TVCC NC* - PIN 2
PIN 3 - TRST or NC* GND - PIN 4
PIN 5 - NC* GND - PIN 6
PIN 7 - TMS/SWDIO GND - PIN 8
PIN 9 - TCK/SWCLK GND - PIN 10
PIN 11 - NC* GND - PIN 12
PIN 13 - NC* GND - PIN 14
PIN 15 - RESET GND - PIN 16
