41 / 54 page  CPL [m] Complement Data Memory Description Each bit of the specified Data Memory is logically complemented (1 ¢s complement). Bits which previously contained a 1 are changed to 0 and vice versa. Operation [m] ¬ [m] Affected flag(s) Z CPLA [m] Complement Data Memory with result in ACC Description Each bit of the specified Data Memory is logically complemented (1 ¢s complement). Bits which previously contained a 1 are changed to 0 and vice versa. The complemented result is stored in the Accumulator and the contents of the Data Memory remain unchanged. Operation ACC ¬ [m] Affected flag(s) Z DAA [m] Decimal-Adjust ACC for addition with result in Data Memory Description Convert the contents of the Accumulator value to a BCD ( Binary Coded Decimal) value re- sulting from the previous addition of two BCD variables. If the low nibble is greater than 9 or if AC flag is set, then a value of 6 will be added to the low nibble. Otherwise the low nibble remains unchanged. If the high nibble is greater than 9 or if the C flag is set, then a value of 6 will be added to the high nibble. Essentially, the decimal conversion is performed by add- ing 00H, 06H, 60H or 66H depending on the Accumulator and flag conditions. Only the C flag may be affected by this instruction which indicates that if the original BCD sum is greater than 100, it allows multiple precision decimal addition. Operation [m] ¬ ACC + 00H or [m] ¬ ACC + 06H or [m] ¬ ACC + 60H or [m] ¬ ACC + 66H Affected flag(s) C DEC [m] Decrement Data Memory Description Data in the specified Data Memory is decremented by 1. Operation [m] ¬ [m] - 1 Affected flag(s) Z DECA [m] Decrement Data Memory with result in ACC Description Data in the specified Data Memory is decremented by 1. The result is stored in the Accu- mulator. The contents of the Data Memory remain unchanged. Operation ACC ¬ [m] - 1 Affected flag(s) Z HALT Enter power down mode Description This instruction stops the program execution and turns off the system clock. The contents of the Data Memory and registers are retained. The WDT and prescaler are cleared. The power down flag PDF is set and the WDT time-out flag TO is cleared. Operation TO ¬ 0 PDF ¬ 1 Affected flag(s) TO, PDF HT82B40R/HT82B40A Rev. 1.70 41 November 5, 2014 |
