BRA

Unconditional Branch

Syntax:

BRA n

Operands:

-1024  n  1023

Operation:

(PC) + 2 + 2n  PC

Status Affected: None

Encoding:

1101 0nnn nnnn nnnn

Description:

Add the 2’s complement number ‘2n’ to

the PC. Since the PC will have incre-

mented to fetch the next instruction, the

new address will be PC + 2 + 2n. This

instruction is a two-cycle instruction.

Bit ‘b’ in register ‘f’ is set.

If ‘a’ is ‘0’, the Access Bank is selected.

If ‘a’ is ‘1’, the BSR is used to select the

GPR bank.

If ‘a’ is ‘0’ and the extended instruction

set is enabled, this instruction operates

in Indexed Literal Offset Addressing

mode whenever f 95 (5Fh). See

Section 25.2.3 “Byte-Oriented and

Bit-Oriented Instructions in Indexed

Literal Offset Mode” for details.
