IPL is 3 bits wide, assigns processor interrupt priority levels from level 0 to level 7.
The U flag is set to 0 when a hardware interrupt request is acknowledged or the INT instruction of
software interrupt numbers 0 to 31 is executed.
If a requested interrupt has higher priority than IPL, the interrupt is enabled.
ISP is selected when the U flag is set to 0; USP is selected when the U flag is set to 1.
If necessary, set to 0. When read, the content is undefined.
The I flag enables maskable interrupts.
Interrupts are disabled when the I flag is set to 0, and are enabled when the I flag is set to 1. The I flag is
set to 0 when an interrupt request is acknowledged.
