# OpenOCD configuration file for:
# FTDI C232HM - USB 2.0 Hi-Speed to MPSSE Cable

# FT232H has single channel, a channel has 16 signals
# This cable outputs only the low signals of FT232H
# low signals[7:0]=GPIOL3-0,TMS,TDO,TDI,TCK
# high signals[7:0]=GPIOH7-0

# ACBUS6/GPIOH6 is connected to red led

# driver for adapters using MPSSE with chips like FT232H
interface ftdi

# vendor and product ID of the adapter
ftdi_vid_pid 0x0403 0x6014
