2. Central Processing Unit (CPU)
2.1.8.7
Interrupt Enable Flag (I Flag)
The I flag enables maskable interrupts.
Maskable interrupts are disabled when the I flag is set to 0, and enabled when it is set to 1. The I flag is
set to 0 when an interrupt request is acknowledged.
2.1.8.8
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 number 0 to 31 is executed.
2.1.8.9
Processor Interrupt Priority Level (IPL)
IPL is a 3-bit register and assigns processor interrupt priority levels from 0 to 7.
If a requested interrupt has higher priority than IPL, the interrupt is enabled.
2.1.8.10
Reserved Space
Only write 0 to bits assigned as reserved bits. The read value is undefined.
