Note: In this ASIC Specification, binary notation, decimal notation and hexadecimal notation are described
according to the rules below.
Binary notation: Double quotation marks are used, e.g., “111000” or “1001”. Otherwise, ‘b’ is appended,
e.g., 111000b.
Hexadecimal notation: ‘0x’ is used, e.g., 0x3F or 0x2D. Otherwise, ‘H’ is appended, e.g., 20H or 1000H.
Decimal notation: Unless binary notation and hexadecimal notation are used, decimal notation is used.
