Units of Measure

A units of measure table is located in the Electrical Specifications
section. Table 9 on page 15 lists all the abbreviations used to
measure the PSoC devices.

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’, ‘b’, or 0x are
decimal.
