bcond

-	The bcond instructions of the device should be specified in the following formats.

-	Bcond disp9

-	Bcond disp17

-	In asrh, the following formats can also be used in addition to the above.

-	bcond9 disp9

-	bcond17 disp17

-	jcond disp9

-	jcond9 disp9

-	jcond17 disp17

jbr disp

-	bcond9 or bcond17 should be specified when output should be with a fixed disp width at all times. These instructions will not be expanded.

-	jcond, jcond9, and jcond17 have the same meaning as bcond, bcond9, and bcond17, respectively.

-	jbr has the same meaning as br.

-	Code that can be specified in cond is shown in "Table 5.28 bcond Instruction".

Table 5.28

bcond Instruction

Instruction	Flag Condition	Meaning of Flag Condition
bgt	( (S xor OV) or Z) = 0	Greater than (signed)
bge	(S xor OV) = 0	Greater than or equal (signed)
blt	(S xor OV) = 1	Less than (signed)
ble	( (S xor OV) or Z) = 1	Less than or equal (signed)
bh	(CY or Z) = 0	Higher (Greater than)
bnl	CY = 0	Not lower (Greater than or equal)
bl	CY = 1	Lower (Less than)
bnh	(CY or Z) = 1	Not higher (Less than or equal)
be	Z = 1	Equal
bne	Z = 0	Not equal
bv	OV = 1	Overflow
bnv	OV = 0	No overflow
bn	S = 1	Negative
bp	S = 0	Positive
bc	CY = 1	Carry
bnc	CY = 0	No carry
bz	Z = 1	Zero
bnz	Z = 0	Not zero
br	---	Always (Unconditional)
bsa	SAT = 1	Saturated

-	The bt and bf instructions cannot be specified in asrh.

-	If the following is specified for disp22, the assembler executes instruction expansion and generates one or more machine-language instructions.

(a)

Absolute expression having a value exceeding the range of -256 to +255 but within the range of -65,536 to +65,535 or a relative expression having a PC offset reference of label with a definition in the same section of the same file as this instruction and having a value exceeding the range of -256 to +255 but within the range of -65,536 to +65,535

Format	Result of Assembly
br disp17	jr disp17
bcond disp17	bcond disp17

(b)

Absolute expression having a value exceeding the range of -65,536 to +65,535 but within the range of -2,097,150 to +2,097,153Note 1, a relative expression having a PC offset reference of label with a definition in the same section of the same file as this instruction and having a value exceeding the range of -65536 to +65535, or a relative expression having a PC offset reference of label without a definition in the same file or section as this instruction.

Format	Result of Assembly

Note 1.

The range of -2,097,150 to +2,097,153 applies to instructions other than br and bsa. The range for the br instruction is from -2,097,152 to +2,097,151, and that for the bsa instruction is from -2,097,148 to +2,097,155.

Note 2.

bncond denotes an instruction that effects control of branches under opposite conditions, for example, bnz for bz or ble for bgt.
