SAM47 INSTRUCTION SET
Flexible Bit Manipulation
In addition to normal bit manipulation instructions like set and clear, the SAM47 instruction set can also perform bit
tests, bit transfers, and bit Boolean operations. Bits can also be addressed and manipulated by special bit
addressing modes. Three types of bit addressing are supported:
— mema.b
— memb.@L
— @H+DA.b
The parameters of these bit addressing modes are described in more detail in Table 5-2.
Instructions Which Have Skip Conditions
The following instructions have a skip function when an overflow or borrow occurs:
XCHI
XCHD
LDI
LDD
If there is an overflow or borrow from the result of an increment or decrement, a skip signal is generated and a skip is
executed. However, the carry flag value is unaffected.
The instructions BTST, BTSF, and CPSE also generate a skip signal and execute a skip when they meet a skip
condition, and the carry flag value is also unaffected.
Instructions Which Affect the Carry Flag
The only instructions which do not generate a skip signal, but which do affect the carry flag are as follows:
ADC
SBC
SCF
RCF
CCF
RRC
