The notation conventions for register names, bit names, numbers, and symbols used in this manual are described
below.
(1) Register Names, Bit Names, and Pin Names
(2) Notation of Numbers
Notation of Numbers and Symbols
Registers, bits, and pins are referred to in the text by symbols. The symbol is accompanied by the word “register,”
“bit,” or “pin” to distinguish the three categories.
Examples
The indication “b” is appended to numeric values given in binary format. However, nothing is appended to the
values of single bits. The indication “h” is appended to numeric values given in hexadecimal format. Nothing is
appended to numeric values given in decimal format.
Examples
the PM03 bit in the PM0 register
P3_5 pin, VCC pin
Binary: 11b
Hexadecimal: EFA0h
Decimal: 1234
