The register bank 0 is selected when the B flag is set to "0". The register bank 1 is selected when this
flag is set to "1".
The O flag is set to "1" when the result of an arithmetic operation overflows; otherwise "0".
The I flag enables a maskable interrupt.
Interrupt is disabled when the I flag is set to "0" and enabled when the I flag is set to "1". The I flag is
set to "0" when an interrupt is acknowledged.
ISP is selected when the U flag is set to "0". USP is selected when this flag is set to "1".
The U flag is set to "0" when a hardware interrupt is acknowledged or the INT instruction of software
interrupt numbers 0 to 31 is executed.
IPL, 3 bits wide, assigns processor interrupt priority levels from level 0 to level 7.
If a requested interrupt has greater priority than IPL, the interrupt is enabled.
When writing to a reserved space, set to "0". When reading, its content is indeterminate.
