44 / 492 page  Only the number of bits required to address the available data memory including external memory (up to 64KB) is implemented for each device. Unused bits will always read as zero. The CPU.SPL and CPU.SPH register pair represents the 16-bit value, CPU.SP. The low byte [7:0] (suffix L) is accessible at the original offset. The high byte [15:8] (suffix H) can be accessed at offset + 0x01. For more details on reading and writing 16-bit registers, refer to Accessing 16-bit Registers. To prevent corruption when updating the Stack Pointer from software, a write to CPU.SPL will automatically disable interrupts for the next four instructions or until the next I/O memory write.

Bits 7:0 – SP[7:0]: Stack Pointer low byte These bits hold the LSB of the 16-bit register. 8.7.3 Status Register The Status register contains information about the result of the most recently executed arithmetic or logic instruction. For details about the bits in this register and how they are affected by the different instructions, see the Instruction Set Summary.
