LJP cc:4, imm:20
cc:4: 4-bit condition code
PC[15:0] ← imm[15:0] if condition is true and the program size is less than 64K word. If the program
is equal to or larger than 64K word, PC[19:0] ← imm[19:0] as long as the condition is true. There
are 16 different conditions that can be used, as described in table 7-6.

%1






LJP cc:4 imm:20 is a 2-word instruction whose immediate field directly specifies the target address
of the jump.

// Assume current PC = 0812h
// Address at 10A5h
After the first instruction is executed, LJP directly jumps to address 10A5h if condition is true.
