Units of Measure
A units of measure table is located in the Electrical Specifications
section. Table 7 on page 14 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 are also 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
decimals.
