6.5 Arithmetic/Logic Unit (ALU)
MC68HC908MR24 — Rev. 4.1
Freescale Semiconductor
C — Carry/Borrow Flag
The ALU performs the arithmetic and logic operations defined by the
instruction set.
Refer to the CPU08 Reference Manual, Freescale document order
number CPU08RM/AD, for a description of the instructions and
addressing modes and more detail about CPU architecture.
The CPU sets the carry/borrow flag when an addition operation
produces a carry out of bit 7 of the accumulator or when a subtraction
operation requires a borrow. Some instructions — such as bit test and
branch, shift, and rotate — also clear or set the carry/borrow flag.
1 = Carry out of bit 7
0 = No carry out of bit 7
