Cautions 1. The lowest bit is fixed to 0.
2. If the values of bits 15 to 1 in stack pointer are smaller than the specified values of bits
15 to 1 in SPUFR, an interrupt signal (INTSPM) is generated.
Stack pointer < SPUFR: INTSPM interrupt signal is generated.
3. When SPMEN = 1, writing to SPUFR is invalid.
