Hi all,is there a limitation on how can I use the serial port pins for ISP programming in the FT232R ?
I will use an 244 tri-state gate, so the pins wont be normally driven, I suppose the FTDI chip has some pull up/down on those pins so that the serial line will operate normally.
The only driven signal is on the /RI pin, with my pullup which controls the /OE on the 244 buffer.
The miso/mosi/sclk/reset can be then really on ANY pin? (cts/rts/dtr/dsr/dcd?)
(The GPIO's are out of question, I want to keep the RX/TX LEDs) Daniel
