SNOS535I – OCTOBER 2000 – REVISED MARCH 2013
A change in program flow requires a non-incremental change in the Program Counter contents. The
Program Counter consists of two bytes, designated the upper byte (PCU) and lower byte (PCL). The most
significant bit of PCU is not used, leaving 15 bits to address the program memory.
Different addressing modes are used to specify the new address for the Program Counter. The choice of
addressing mode depends primarily on the distance of the jump. Farther jumps sometimes require more
instruction bytes in order to completely specify the new Program Counter contents.
The available transfer-of-control addressing modes are:
Jump Relative
Jump Absolute
Jump Absolute Long
Jump Indirect
The transfer-of-control addressing modes are described below. Each description includes an example of a
Jump instruction using a particular addressing mode, and the effect on the Program Counter bytes of
executing that instruction.
Jump Relative. In this 1-byte instruction, six bits of the instruction opcode specify the distance of the jump
from the current program memory location. The distance of the jump can range from
31 to +32. A JP+1
instruction is not allowed. The programmer should use a NOP instead.
Example:
Jump Relative
JP 0A

PCL
05 Hex
0F Hex
Jump Absolute. In this 2-byte instruction, 12 bits of the instruction opcode specify the new contents of the
Program Counter. The upper three bits of the Program Counter remain unchanged, restricting the new
Program Counter address to the same 4-kbyte address space as the current instruction. (This restriction is
relevant only in devices using more than one 4-kbyte program memory space.)
