USER’S MANUAL
An MIOS 16-bit parallel port I/O submodule (MPIOSM) can handle up to 16 input/out-
put pins. Its control register is composed of two 16-bit registers: the data register (DR)
and the data direction register (DDR). Each pin of the MPIOSM may be programmed
as an input or an output under software control. The direction of a pin is determined by
the state of the corresponding bit in the DDR.
Refer to
One set of registers is associated with the MPIOSM submodule. The base addresses
of the submodules are given in the table below.
This read/write register defines the value to be driven to the pad in output mode, for
each implemented I/O pin of the MPIOSM.
