2. Central Processing Unit (CPU)
2.8.8
Stack Pointer Select Flag (U Flag)
ISP is selected when the U flag is 0. USP is selected when the U flag is 1.
The U flag becomes 0 when a hardware interrupt request is accepted, or the INT instruction of software
interrupt number 0 to 31 is executed.
2.8.9
Processor Interrupt Priority Level (IPL)
IPL is 3 bits wide and assigns processor interrupt priority levels from 0 to 7.
If a requested interrupt has higher priority than IPL, the interrupt request is enabled.
2.8.10
Reserved Areas
Only set these bits to 0. The read value is undefined.
