NAME	CMP2 -- Compare register against upper and lower bounds (68020+)
SYNOPSIS	CMP2 <ea>,Rn
FUNCTION	Used to compare value of Rn (Dn or An) with two lower and upper bounds, which are stored in memory, at address given by <ea> (in two adjacent areas). Lower bound have to be stored before upper bound. Flags are set following to the result of comparison. If Rn is a data register Dn, and if operation is made on 8 or 16 bits, only the 8 or 16 bits of Dn are taken in count. In opposite, in the case of Rn as an address register and if a 16 bits operation is granted, the 32 bits of An are compared to bounds which are, them, extended on 32 bits by their signs.

REGISTER	Register specifies the register Rn which contains the value to test. If D/A = 0: Rn = Dn If D/A = 1: Rn = An <ea> specifies bounds, addressing modes allowed are: Addressing Mode Mode Register Dn - - An - - (An) 010 No reg. An (An)+ - - -(An) - - (d16,An) 101 No reg. An (d8,An,Xi) 110 No reg. An (bd,An,Xi) 110 No reg. An ([bd,An,Xi]od) 110 No reg. An ([bd,An],Xi,od) 110 No reg. An Addressing Mode Mode Register Abs.W 111 000 Abs.L 111 001 (d16,PC) 111 010 (d8,PC,Xi) 111 011 (bd,PC,Xi) 111 011 ([bd,PC,Xi],od) 111 011 ([bd,PC],Xi,od) 111 011 #data - -
SIZE	00-> one Byte operation 01-> one Word operation 10-> one Long operation
RESULT	X - Not affected N - Undefined. Z - Set if Rn is equal to one of the two bounds. Cleared otherwise. V - Undefined. C - Set if Rn is out of bounds. Cleared otherwise.
