FUNCTION: Input Interrupt
DESCRIPTION:
The II command enables the interrupt function for the specified inputs. By default, input
interrupts are configured for activation with a logic "0" but can be configured for
activation with a logic "1" signal.
If any of the specified inputs are activated during program execution, the program will jump
to the subroutine with label #ININT. Any trippoints set by the program will be cleared
but can be re-enabled by the proper termination of the interrupt subroutine using RI. The
RI command is used to return from the #ININT routine.
Note: An application program must be running on the controller for the interrupt function to
work.
ARGUMENTS: II m,n,o,p
where
m is an integer between 0 and 8 decimal. 0 disables interrupt. The value of m specifies the
lowest input to be used for the input interrupt. When the 2
nd
argument, n, is omitted, only
the input specified by m will be enabled.
n is an integer between 2 and 8. This argument is optional and is used with m to specify a
range of values for input interrupts. For example, II 2,4 specifies interrupts occurring for
Input 2, Input 3 and Input 4.
o is an integer between 1 and 255. Using this argument is an alternative to specifying an input
range with m,n. If m and n are specified, o will be ignored. The argument o is an integer
value and represents a binary number. For example, if o = 15, the binary equivalent is
00001111 where the bottom 4 bits are 1 (bit 0 through bit 3) and the top 4 bits are 0 (bit 4
through bit 7). Each bit represents an interrupt to be enabled - bit0 for interrupt 1, bit 1
for interrupt 2, etc. If o=15, the inputs 1,2,3 and 4 would be enabled.
p is an integer between 1 and 255. The argument p is used to specify inputs that will be
activated with a logic "1". This argument is an integer value and represents a binary
number. This binary number is used to logically "AND" with the inputs which have been
specified by the parameters m and n or the parameter o. For example, if m=1 and n=4,
the inputs 1,2,3 and 4 have been activated. If the value for p is 2 (the binary equivalent of
2 is 00000010), input 2 will be activated by a logic `1' and inputs 1,3, and 4 will be
activated with a logic "0".
