Bit 7: Stack pointer select flag (U flag)
Interrupt stack pointer (ISP) is selected when this flag is “0” ; user stack pointer (USP) is selected
when this flag is “1”.
This flag is cleared to “0” when a hardware interrupt is acknowledged or an INT instruction of software
interrupt Nos. 0 to 31 is executed.
Bits 8 to 11: Reserved area
Bits 12 to 14: Processor interrupt priority level (IPL)
Processor interrupt priority level (IPL) is configured with three bits, for specification of up to eight
processor interrupt priority levels from level 0 to level 7.
If a requested interrupt has priority greater than the processor interrupt priority level (IPL), the interrupt
is enabled.
Bit 15: Reserved area
The C, Z, S, and O flags are changed when instructions are executed. See the software manual for
details.
