BS86DH12C
High Voltage Touch A/D Flash MCU with HVIO
NOP No operation
Description No operation is performed. Execution continues with the next instruction.
Operation No operation
Affected flag(s) None
OR A,[m] Logical OR Data Memory to ACC
Description Data in the Accumulator and the specified Data Memory perform a bitwise
logical OR operation. The result is stored in the Accumulator.
Operation ACC ← ACC "OR" [m]
Affected flag(s) Z
Logical OR immediate data to ACC
OR A,x
Description Data in the Accumulator and the specified immediate data perform a bitwise logical OR
operation. The result is stored in the Accumulator.
Operation ACC ← ACC "OR" x
Affected flag(s) Z
ORM A,[m] Logical OR ACC to Data Memory
Description Data in the specified Data Memory and the Accumulator perform a bitwise logical OR
operation. The result is stored in the Data Memory.
Operation [m] ← ACC "OR" [m]
Affected flag(s) Z
Return from subroutine
RET
Description The Program Counter is restored from the stack. Program execution continues at the restored
address.
Operation Program Counter ← Stack
Affected flag(s) None
RET A,x Return from subroutine and load immediate data to ACC
Description The Program Counter is restored from the stack and the Accumulator loaded with the specified
immediate data. Program execution continues at the restored address.
Operation Program Counter ← Stack
ACC ← x
Affected flag(s) None
RETI Return from interrupt
Description The Program Counter is restored from the stack and the interrupts are re-enabled by setting the
EMI bit. EMI is the master interrupt global enable bit. If an interrupt was pending when the
RETI instruction is executed, the pending Interrupt routine will be processed before returning
to the main program.
Operation Program Counter ← Stack
EMI ← 1
Affected flag(s) None
RL [m] Rotate Data Memory left
Description The contents of the specified Data Memory are rotated left by 1 bit with bit 7 rotated into bit 0.
Operation [m].(i+1) ← [m].i; (i=0~6)
[m].0 ← [m].7
Affected flag(s) None
