tc(BYTE) max = ( + + + ) where boxed numbers refer to the max values for corresponding parameters in the above table (for example,
means the value under max for parameter 6 in the table — a value of 10 ns). This assumes that two ’C40s are connected.
* On products compliant to MIL-PRF-38535, this parameter is not production tested.
NOTE 12: Communication port timing does not include line length delay.
