140 / 152 page  OR A,x Logical OR immediate data to ACC 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 ²OR² 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 ²OR² [m] Affected flag(s) Z RET Return from subroutine Description The Program Counter is restored from the stack. Program execution continues at the re- stored 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 set- ting the EMI bit. EMI is the master interrupt global enable bit. If an interrupt was pend- ing 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 RLA [m] Rotate Data Memory left with result in ACC Description 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 Mem- ory remain unchanged. Operation ACC.(i+1) ¬ [m].i; (i = 0~6) ACC.0 ¬ [m].7 Affected flag(s) None Rev. 1.20 140 September 15, 2011 HT45F23/HT45F43 8-Bit Flash MCU with Op Amps & Comparators |
