²Alternate mnemonics are provided as a way of improving source code readability. They generate the same opcode as the original mnemonic. For example, JA (jump above) tests the same conditions as JNBE (jump not below or equal) but may have more meaning in a specific section of code.

Example 4.14.27.1	JNZ 0x2010

Jump to program memory location 0x2010 if the result is not zero.

Example 4.14.27.2

JE 0x2010, R3++R5

Jump to program memory location 0x2010 if flag RZF = 1. Increment R3 by R5. Since this jump instruction does not have a P at the end, post-modification is NOT reflected in the STAT register. Thus, if R3 becomes zero, RZF is not updated.

Example 4.14.27.3

JIN1 0x2010, R1±±

Jump to program memory location 0x2010 if I/O port address PD0 pin has a value of 1. Decrement R1 by 2.

Example 4.14.27.4

JTAG 0x2010, R2++

Jump to program memory location 0x2010 if TAG bit of STAT is zero. Increment R2 by 2.
