Mode #6, #7 - Simple Boundary Scan 1 and Scan 2
The HI2303 has a simple boundary scan function.
Clamp Function
The following two points should be noted when using the
digital clamp circuit.
- The clamp pulse must be supplied externally.
- The clamp circuit is not designed for V cycle clamping.
16 different reference levels can be selected for the digital
clamp circuit through a combination of the REF0, REF1,
REF2 and REF3 inputs as shown in the table below. Note
that the REF0, REF1, REF2 and REF3 input signals are
fetched asynchronously with the clock input signal.
