is a 1 or 0, 1 for outputs and 0 for inputs. The x is the bank number
OP
m,n,o,p,q
m = 8 standard digital outputs
n = extended I/O banks 0 & 1, outputs 17-32
o = extended I/O banks 2 & 3, outputs 33-48
p = extended I/O banks 4 & 5, outputs 49-64
q = extended I/O banks 6 & 7, outputs 65-80
SB n Sets the output bit to a logic 1, n is the number of the output from 1 to 80.
CB n Clears the output bit to a logic 0, n is the number of the output from 1 to 80.
OB n,m Sets the state of an output as 0 or 1, also able to use logical conditions.
TI n Returns the state of 8 digital inputs as binary converted to decimal, n is the bank
number +2.
_TI n Operand (internal variable) that holds the same value as that returned by TI n.
@IN[n] Function that returns state of individual input bit, n is number of the input from 1 to
80.
