4.4.1 MPSSE Adaptive Clocking
Adaptive clocking is a new MPSSE feature added to the FT24232H MPSSE engine.
The mode is effectively handshaking the CLK signal with a return clock RTCK. This is a technique used by
ARM processors.
The FT4232H will assert the CLK line and wait for the RTCK to be returned from the target device to
GPIOL3 line before changing the TDO (data out line).
