2. Central Processing Unit (CPU)
2.8.7
Interrupt Enable Flag (I Flag)
The I flag enables a maskable interrupt.
An interrupt is 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.
2.8.8
Stack Pointer Select Flag (U Flag)
ISP is selected when the U flag is set to “0”, USP is selected when the U flag is set to “1”.
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.
2.8.9
Processor Interrupt Priority Level (IPL)
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.
2.8.10
Reserved Bit
When write to this bit, set to “0”. When read, its content is indeterminate.
