[Reference 1] CALL20
1) When label20-PC-2 is from -0x800 to +0x7fe, an instruction is created as follows:
CALL label12
2) When label20-PC-2 is outside of the range in 1) and includes an external reference
symbol, an instruction is created as follows:
LDI:20 #label20,Ri
CALL @Ri
[Reference 2] BRA20
1) When label20-PC-2 is from -0x100 to +0xfe, an instruction is created as follows:
BRA label9
2) When label20-PC-2 is outside of the range in 1) and includes an external reference
symbol, an instruction is created as follows:
LDI:20 #label20,Ri
JMP @Ri
[Reference 3] Bcc20
1) When label20-PC-2 is from -0x100 to +0xfe, an instruction is created as follows:
Bcc label9
