STB032xx and STB034xx Digital Set-Top Box Integrated Controllers
STB03xxx Multiplexed I/O Signal Table
STB03xxx has four sets of multiplexed I/O signals: Mux0, Mux1, Mux2, and Mux3. At reset, the
multiplexed I/O signals are tristated, unless noted.
The muxtiplexed I/O can be selected by column in the following tables. For example, if Input/Output 1 is
selected, Input/Output 2 and Input/Output 3 are not available.
Blank entries indicate reserved multiplexing.
