ARM-USB-TINY-H high-Z output

[krolikB]

Hi all! Please help me with the following:

1. what is the schematic of TTDI/TTDO/TTCK/TTMS pins inside of ARM-USB-TINY-H ?
2. Could I have high-Z state on these pins when I don't use the tool ?

I'd like to use this tool as an SPI adapter for programming and let it release the bus and stay connected. Is this possible? If not, may I use ARM-USB-OCD-H for this purpose ?

1. These are just connected to the FTDI chip inside - FT2232H. There is some passive protection.

2. It should be possilbe. Refer to the OpenOCD options. Search for "Hi-Z" in the document here: http://openocd.org/doc/pdf/openocd.pdf
