ADSP-SC58x PINT Register Descriptions
PINT Assign Register
The
register controls the pin-to-interrupt request assignment in a byte-wide manner. This register
PINT_ASSIGN
consists of four control bytes that each function as a multiplexer control.
The PINT ports are subdivided into 8-bit half ports, resulting in lower and upper half 8-bit units. Using the multi-
plexers controlled by the
0 or byte 2 of either associated PINT block. The upper half units can be forwarded to either byte 1 or byte 3 of the
PINT block, without further restrictions.
