5.3.1 Program Counter (PC)
The 16-bit Program Counter (PC/R0) points to the next instruction to be executed. Each instruction uses an even
number of bytes (two, four, or six), and the PC is incremented accordingly. Instruction accesses in the 64-KB address
space are performed on word boundaries, and the PC is aligned to even addresses. The PC can be addressed with
all instructions and addressing modes.
5.3.2 Stack Pointer (SP)
The Stack Pointer (SP/R1) is used by the CPU to store the return addresses of subroutine calls and interrupts. It uses
a pre-decrement, post-increment scheme. In addition, the SP can be used by software with all instructions and ad-
dressing modes. The SP is initialized into RAM by the user, and is aligned to even addresses.
5.3.3 Status Register (SR)
The Status Register (SR/R2), used as a source or destination register, can be used in the register mode only ad-
dressed with word instructions. The remaining combinations of addressing modes are used to support the con-
stant generator.
