75 / 86 page  Rev. 1.00 74 October 27, 2011 Rev. 1.00 75 October 27, 2011 HT82B42R/HT82B42RE I/O MCU with USB Interface Logical OR Data Memory to ACC Data in the Accumulator and the specified Data Memory perform a bitwise logical OR operation. The result is stored in the Accumulator. ACC ← ACC "OR" [m] Z Logical OR immediate data to ACC Data in the Accumulator and the specified immediate data perform a bitwise logical OR operation. The result is stored in the Accumulator. ACC ← ACC "OR"x Z Logical OR ACC to Data Memory Data in the specified Data Memory and the Accumulator perform a bitwise logical OR operation. The result is stored in the Data Memory. [m] ← ACC "OR"[m] Z Return from subroutine The Program Counter is restored from the stack. Program execution continues at the restored address. Program Counter ← Stack 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 ← Stack ACC ← x None Return from interrupt 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. Program Counter ← Stack EMI ← 1 None Rotate Data Memory left The contents of the specified Data Memory are rotated left by 1 bit with bit 7 rotated into bit 0. [m].(i+1) ← [m].i; (i = 0~6) [m].0 ← [m].7 None OR A,[m] Description Operation Affected flag(s) OR A,x Description Operation Affected flag(s) ORM A,[m] Description Operation Affected flag(s) RET Description Operation Affected flag(s) RET A,x Description Operation Affected flag(s) RETI Description Operation Affected flag(s) RL [m] Description Operation Affected flag(s) |
