Description

This directive forces the next instruction to a boundary that is a multiple of <n>, relative to the start of the section. The value of <n> must be a positive number between 1 and 32767. The ALIGN directive can force alignment to any size. The filling bytes inserted for alignment purpose are initialized with `\0'.

ALIGN can be used in code or data sections.

Example

The example shown in the following listing, aligns the HEX label to a location, which is a multiple of 16 (in this case, location 00010 (Hex))
