Logical OR immediate data to ACC
Data in the Accumulator and the specified immediate data perform a bitwise logical OR op-
eration. The result is stored in the Accumulator.
ACC
Z
Logical OR ACC to Data Memory
Data in the specified Data Memory and the Accumulator perform a bitwise logical OR oper-
ation. The result is stored in the Data Memory.

Return from subroutine
The Program Counter is restored from the stack. Program execution continues at the re-
stored address.
Program Counter
None
Return from subroutine and load immediate data to ACC
The Program Counter is restored from the stack and the Accumulator loaded with the
specified immediate data. Program execution continues at the restored address.
Program Counter
ACC
None
Return from interrupt
The Program Counter is restored from the stack and the interrupts are re-enabled by set-
ting the EMI bit. EMI is the enable master (global) interrupt bit (bit 0; register INTC). If an in-
terrupt was pending when the RETI instruction is executed, the pending Interrupt routine
will be processed before returning to the main program.

Rotate Data Memory left
The contents of the specified Data Memory are rotated left by 1 bit with bit 7 rotated into bit
0.

Rotate Data Memory left with result in ACC
The contents of the specified Data Memory are rotated left by 1 bit with bit 7 rotated into bit
0. The rotated result is stored in the Accumulator and the contents of the Data Memory re-
main unchanged.
