2.4.5
Reset exception handling loads the CPU's program counter (PC) from the vector table, clears the
trace (T) bit in EXR to 0, and sets the interrupt mask (I) bits in CCR and EXR to 1. The other
CCR bits and the general registers are not initialized. Note that the stack pointer (ER7) is
undefined. The stack pointer should therefore be initialized by an MOV.L instruction executed
immediately after a reset.

Description
Carry Flag
Set to 1 when a carry occurs, and cleared to 0 otherwise.
Used by:
•

•
The carry flag is also used as a bit accumulator by bit
manipulation instructions.
Add instructions, to indicate a carry
Subtract instructions, to indicate a borrow
Shift and rotate instructions, to indicate a carry
