Throughout this help file:

  • Hexadecimal numbers are prefixed with a dollar sign (e.g. $A5).

  • "Word" refers to a two-byte integer.

  • "Long word" refers to a four-byte integer.

  • Multi-byte integers are always encoded in little-endian notation (e.g. the hex word $1234 would be represented in memory by $34, $12 and the long word 123456789 would be encoded as $15, $CD, $5B, $07).

  • All numeric fields are unsigned integers unless stated otherwise. In numeric fields that support them, negative numbers are represented in two's-compliment form.

  • mod indicates modulo. So if an entry says "n mod 4 = 0," this indicates that n is a multiple of 4 (i.e. 0, 4, 8...).
