+# Created on 20220410 by CeDeROM Tomasz CEDRO (www.cederom.io).
+# Interface DataSheet: https://kristech.pl/files/KT-LINK-UM-ENG.pdf
+# AVRDUDE FT2232H PIN NUMBER DECODE:
+# | 0 | 1 | .. | 7 | 8 | 9 | .. | 15 |
+# | ADBUS0 | ADBUS1 | .. | ADBUS7 | ACBUS0 | ACBUS1 | .. | ACBUS7 |
+# KT-LINK JTAG CONN:
+# 1=Vsense(->EXT13), 19=5V(EXT1->EXT3), 20=GND, 3=TPIRST, 9=TPICLK, 7=TPIDATA.
+# INTERNALS CONFIGURATION ("~" MEANS ACTIVE LOW):
+# ~TRST_EN=10(ACBUS2), ~CLK_EN=14(ACBUS6), ~MOSI_EN=13(ACBUS5),
+# TMS_SEL=5(ADBUS5), ~TMS_EN=12(ACBUS4), LED=~15(ACBUS7).
+# CONNECTION NOTES:
+# * Connect EXT connector pin 1 with 3 to get 5V on JTAG connector pin 19.
+# * Connect JTAG connector pin 1 to 5V (i.e. EXT pin 13 or JTAG pin 19).
+# * For TPI connection use resistors: TDO --[470R]-- TPIDATA --[470R]-- TDI.
+# * Powering target from JTAG pin 19 allows KT-LINK current measurement.
