jr22

Unconditional branch (PC relative).

[Syntax]

-	jr22 disp22

The following can be specified for disp22:

-	Absolute expression having a value of up to 22 bits

-	Relative expression having a PC offset reference of label

[Function]

Transfers control to the address attained by adding the current program counter (PC) value and the relative or absolute expression value specified by the operand.

[Description]

-	If the following is specified for disp22, the assembler generates one jr machine instructionNote.

(a)	Absolute value in the range of -2,097,152 to +2,097,151

(b)	Relative expression that has a PC offset reference of label

Note	The jr machine instruction takes an immediate value in the range of -2,097,152 to +2,097,151 (0xFE00000 to 0x1FFFFF) as the displacement.

[Caution]

-	If an absolute expression that exceeds the range of -2,097,152 to +2,097,151 is specified as disp22, the assembler outputs the following message and stops assembling.

E0550230 : illegal operand (range error in displacement)

-	If an absolute expression having an odd-numbered value is specified as disp22, the assembler outputs the following message and stops assembling.

E0550226 : illegal operand (must be even displacement)
