Figure 10-3: Data ports and related signals
Combined ports (ports E, F, G, H)
A combination of ports A / B and ports C /D provides two additional 16-bit and 8-bit-
wide bidirectional ports. The combined ports are termed ports E and F, respectively. A
combination of ports A / B / C and ports A / B / C / D provides two 20-bit and 24-bit-
wide bidirectional ports. These combined ports are termed ports G and H.
Figure 10-4: Definition of ports E, F, G, H
The properties of the combined ports are as follows:
●
The signal direction (input or output) is according to the configuration of ports A, B,
C, and D. E.g. to write data to port G (H), ports A, B, and C (A, B, C, and D) must
be configured as output ports.
●
Data can be read and written using the
CONTrol:HANDler:E|F|G|H[:DATA]
commands.
●
The bit order is D3 ... D0 C3 ... C0 (port E), B7 ... B0 A7 ... A0 (port F), C3 ... C0
B7 ... B0 A7 ... A0 (port G), and D3 ... D0 C3 ... C0 B7 ... B0 A7 ... A0 (port H).
