I/O MCU with USB Interface

Skip if bit i of Data Memory is 0

If bit i of the specified Data Memory is 0, the following instruction is skipped. As

this requires the insertion of a dummy instruction while the next instruction is

fetched, it is a two cycle instruction. If the result is not 0, the program proceeds

with the following instruction.

Skip if [m].i = 0

None

Read table (current page) to TBLH and Data Memory

The low byte of the program code (current page) addressed by the table pointer

(TBLP) is moved to the specified Data Memory and the high byte moved to TBLH.

[m] ← program code (low byte)

TBLH ← program code (high byte)

None

Move the ROM code (locate by TBLP and TBHP) to TBLH and data memory (ROM

code TBHP is enabled)

The low byte of ROM code addressed by the table pointers (TBLP and TBHP)

is moved to the specified data memory and the high byte transferred to TBLH

directly.

[m] ← program code (low byte)

TBLH ← program code (high byte)

None

Read table (last page) to TBLH and Data Memory

The low byte of the program code (last page) addressed by the table pointer (TBLP)

is moved to the specified Data Memory and the high byte moved to TBLH.

[m] ← program code (low byte)

TBLH ← program code (high byte)

None

Logical XOR Data Memory to ACC

Data in the Accumulator and the specified Data Memory perform a bitwise logical

XOR operation. The result is stored in the Accumulator.

ACC ← ACC "XOR" [m]

Logical XOR ACC to Data Memory

Data in the specified Data Memory and the Accumulator perform a bitwise logical

XOR operation. The result is stored in the Data Memory.

[m] ← ACC "XOR" [m]

Logical XOR immediate data to ACC

Data in the Accumulator and the specified immediate data perform a bitwise

logical XOR operation. The result is stored in the Accumulator.

ACC ← ACC "XOR" x

SZ [m].i
