80 / 86 page ![]() Rev. 1.00 80 October 27, 2011 Rev. 1.00 81 October 27, 2011 HT82B42R/HT82B42RE 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] Z 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] Z 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 Z SZ [m].i Description Operation Affected flag(s) TABRDC [m] Description Operation Affected flag(s) TABRDC [m] Description Operation Affected flag(s) TABRDL [m] Description Operation Affected flag(s) XOR A,[m] Description Operation Affected flag(s) XORM A,[m] Description Operation Affected flag(s) XOR A,x Description Operation Affected flag(s) |
