Note:
1. The pull down pins and XTI are not included.
2. The pull down pins (typ. 150kΩ) is as follows: 1, 2, 18, 19, 20, 21, 22, 30, 46, 47, and 48.

Note: Regarding the input/output levels in the text, the low level will be represented as "L" or 0, and the
high level as "H" or 1.
In principle, "0" and "1" will be used to represent the bus functions (serial/parallel) such as registers.
