NOTE The pinout tables in Chapter 3 of this manual identify pin sequence using the
following methods: A 20-pin header with two rows of pins, using odd/even
numbering, where pin 2 is directly across from pin 1, is noted as 20-pin, 2 rows,
odd/even (1, 2). Alternately, a 20-pin connector using consecutive numbering,
where pin 11 is directly across from pin 1, is noted in this way: 20-pin, 2 rows,
consecutive (1, 11). The second number in the parenthesis is always directly
across from pin 1. See
Figure 2-5 .
