Where edge_value is either RISING or FALLING.
LEVEL
The level sensitivity of an interrupt signal is specified by the LEVEL keyword. Its use is
deprecated. Please use the SENSITIVITY keyword.
Format
PORT interrupt = "", DIR=O, LEVEL=level_value, SIGIS=INTERRUPT
Where the level_value is either HIGH or LOW.
SENSITIVITY
The interrupt sensitivity of an interrupt signal is specified by the SENSITIVITY keyword.
This supersedes the EDGE and LEVEL keywords.
Format
PORT interrupt = "", DIR=O, SENSITIVITY=value, SIGIS=INTERRUPT
Where the value is either EDGE_FALLING, EDGE_RISING, LEVEL_HIGH or
LEVEL_LOW.
SIGIS
The class of a signal is specified by the SIGIS keyword.
Format
PORT mysig = "", DIR=O, SIGIS=value
