1: For the setting method, refer to the section 1.3.1.
2: Pin number of 1 indicates that of the left-hand side connector, and pin number of 2 indicates that of the right-hand
side connector.
3: Selection of left-hand (F) side provides the first half (X00 to X1F) LED indications, and selection of right-hand (L) side provides the
latter half (X20 to X3F) LED indications.
4: When using A6CON2 or A6CON3, refer to Chapter 7.
