Reference 1: CALL32:D
1) When label32-PC-2 is -0x800 - +0x7fe, the instruction is generated as follows.

CALL:D label12

2) When label32-PC-2 is outside the area as per 1) and includes an external reference symbol, the command is generated as

follows.

LDI:32 #label32,Ri
CALL:D @Ri

Reference 2: BRA32:D
1) When label32-PC-2 is - 0x100 - + 0xfe, the instruction is generated as follows.

BRA:D label9

2) When label32-PC-2 is outside the area as per 1) and includes an external reference symbol, the command is generated as

follows.

LDI:32 #label32,Ri
JMP:D @Ri

Reference 3: Bcc32:D
1) When label32-PC-2 is - 0x100 - + 0xfe, the instruction is generated as follows.

Bcc:D label9

2) When label32-PC-2 is outside the area as per 1) and includes an external reference symbol, the command is generated as

follows.

Bxcc false xcc is a contradiction condition of cc.
