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 enCoRe V 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.
