ISP is selected when the U flag is “0”; USP is selected when the U flag is “1”.
The U flag is cleared to “0” when a hardware interrupt request is accepted or an INT instruction for software
interrupt Nos. 0 to 31 is executed.
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 IPL, the interrupt is enabled.
When write to this bit, write “0”. When read, its content is indeterminate.
