17.11.8.2 MPIOSM Data Direction Register (MPIOSMDDR)
17.12 MIOS14 Interrupts
This section describes the interrupt functions of the MIOS14 and its submodules and how these interrupts
are passed to the CPU via the peripheral bus. Interrupt requests from the MIOS14 are treated as exceptions
by the CPU and are dealt with by the CPU’s exception processing routines. For a more detailed description
of exception processing in the relevant microprocessors, please refer
and to the RCPU Reference Manual.
17.12.1 MIOS14 Interrupt Structure
The MIOS14 and its submodules are capable of generating interrupts on different levels to be transmitted
to the CPU via the peripheral bus. Inside the MIOS14, all the information required for requesting and
servicing the interrupts are treated in two different sections:
The MIRSM gathers in service request flags from each group of up to 16 submodules and transfers those
requests to the MIOS14 interrupt control section (ICS).

These bits are read/write data bits that define the data direction status for each implemented I/O
signal of the MPIOSM
0 = corresponding signal is input.
1 = corresponding signal is output.

These bits are read/write data bits that define the value to be driven to the pad in output mode,
for each implemented I/O signal of the MPIOSM. The Msb is 15, Lsb is 0.
