7. Document Conventions
7.1 Acronyms Used
The following table lists the acronyms that are used in this
document.
7.2 Units of Measure
A units of measure table is located in the Electrical Specifications
section. Table 10-1 on page 21 lists all the abbreviations used to
measure the PSoC devices.
7.3 Numeric Naming
Hexadecimal numbers are represented with all letters in
uppercase with an appended lowercase ‘h’ (for example, ‘14h’ or
‘3Ah’). Hexadecimal numbers may also be represented by a ‘0x’
prefix, the C coding convention. Binary numbers have an
appended lowercase ‘b’ (for example, ‘01010100b’ or
‘01000011b’). Numbers not indicated by an ‘h’ or ‘b’ are decimal.
