NOTE
The pinout tables in Chapter 3 of this manual identify pin sequence using the
following method: A 10-pin header with two rows of pins, using odd/even
numbering, where pin 2 is directly across from pin 1, is noted as 10-pin, 2 rows, odd/
even (1, 2).Alternately, a 10-pin connector using consecutive numbering, where pin
6 is directly across from pin 1, is noted in this way: 10-pin, 2 rows, consecutive (1,
6). The second number in the parenthesis is always directly across from pin-1. See
