SBC A,[m]  
Subtract Data Memory from ACC with Carry  
Description  
The contents of the specified Data Memory and the complement of the carry flag are sub-  
tracted from the Accumulator. The result is stored in the Accumulator. Note that if the result  
of subtraction is negative, the C flag will be cleared to 0, otherwise if the result is positive or  
zero, the C flag will be set to 1.  
Operation  
ACC ¬ ACC - [m] - C  
Affected flag(s)  
OV, Z, AC, C  
SBCM A,[m]  
Subtract Data Memory from ACC with Carry and result in Data Memory  
Description  
The contents of the specified Data Memory and the complement of the carry flag are sub-  
tracted from the Accumulator. The result is stored in the Data Memory. Note that if the re-  
sult of subtraction is negative, the C flag will be cleared to 0, otherwise if the result is  
positive or zero, the C flag will be set to 1.  
Operation  
[m] ¬ ACC - [m] - C  
Affected flag(s)  
OV, Z, AC, C  
SDZ [m]  
Skip if decrement Data Memory is 0  
Description  
The contents of the specified Data Memory are first decremented by 1. If the result 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.  
Operation  
[m] ¬ [m] - 1  
Skip if [m] = 0  
Affected flag(s)  
None  
SDZA [m]  
Skip if decrement Data Memory is zero with result in ACC  
Description  
The contents of the specified Data Memory are first decremented by 1. If the result is 0, the  
following instruction is skipped. The result is stored in the Accumulator but the specified  
Data Memory contents remain unchanged. As this requires the insertion of a dummy in-  
struction 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.  
Operation  
ACC ¬ [m] - 1  
Skip if ACC = 0  
Affected flag(s)  
None  
SET [m]  
Set Data Memory  
Description  
Operation  
Each bit of the specified Data Memory is set to 1.  
[m] ¬ FFH  
Affected flag(s)  
None  
SET [m].i  
Set bit of Data Memory  
Description  
Operation  
Bit i of the specified Data Memory is set to 1.  
[m].i ¬ 1  
Affected flag(s)  
None
