Units of Measure

A units of measure table is located in the Electrical Specifica- tions section. Table 3-1 on page 13 lists all the abbreviations used to measure the PSoC devices.

Numeric Naming

Hexidecimal numbers are represented with all letters in upper- case with an appended lowercase ‘h’ (for example, ‘14h’ or ‘3Ah’). Hexidecimal numbers may also be represented by a ‘0x’ prefix, the C coding convention. Binary numbers have an appended lowercase ‘b’ (e.g., 01010100b’ or ‘01000011b’). Numbers not indicated by an ‘h’ or ‘b’ are decimal.
