# Specifies the initial values of the FTDI GPIO data and direction registers. 
# Each value is a 16-bit number corresponding to the concatenation of the 
# high and low FTDI GPIO registers. The values should be selected based on 
# the schematics of the adapter, such that all signals are set to safe levels
# with minimal impact on the target system. Avoid floating inputs, 
# conflicting outputs and initially asserted reset signals.
