6.4.4 Program Counter
MC68HC908MR8 — Rev 4.1
Freescale Semiconductor
The program counter (PC) is a 16-bit register that contains the address
of the next instruction or operand to be fetched.
Normally, the program counter automatically increments to the next
sequential memory location every time an instruction or operand is
fetched. Jump, branch, and interrupt operations load the program
counter with an address other than that of the next sequential location.
During reset, the program counter is loaded with the reset vector
address located at $FFFE and $FFFF. The vector address is the
address of the first instruction to be executed after exiting the reset state.
