ADSP-214xx SHARC Processor Hardware Reference 9-13
Digital Application/Digital Peripheral Interfaces
3.
MISCxx_I input sources collected from different groups.
4. Some buffers allow signal inversion.
The miscellaneous buffers acts as intermediate buffer connections between
the peripheral’s source node and the pin buffer enable destination node.
This allows for routing that are not possible among a single group.
The miscellaneous buffer allows interconnects which are not sup-
ported within a DAI/DPI routing group.
Table 9-2 and Table 9-3 provide routing options for the DAI and DPI
miscellaneous buffers. Note that while the Interrupt and Miscellaneous
Inputs have different naming conventions, they are the same physical
input field.
