Style #2: (two columns required)
The types are IO_PI and IO_PO. IO_PI is the input value and IO_PO is the output
value. Both the pin names must be the same as the inout pin name.
Style #3: (only one column required)
The type is IO_HL. If the value is H, L, or Z, it is the output value. Otherwise, it is
the input value. The following describes the behavior of each symbol:
•0 = driving 0, measure X.
•1 = driving 1, measure X.
•X = driving X, measure X.
•Z = driving Z, measure X.
•H = driving Z, measure 1.
•L = driving Z, measure 0.
Style #4: (only one column required)
The type is IO_10. IO_10 is used for a primary inout pin. If the value is 0, 1, or Z,
it is the output value. If the value is H, L, or X, it is the input value. The IO_10
format is opposite to the IO_HL format.
•L = driving 0, measure X.
•H = driving 1, measure X.
•X = driving X, measure X.
•Z = driving Z, measure X.
•1 = driving Z, measure 1.
•0 = driving Z, measure 0.
