CHAPTER 4: PERIPHERAL CIRCUITS AND OPERATION (Interrupt and HALT)
4.16.1 Interrupt factors
Table 4.16.1.1 shows the factors for generating interrupt requests.
The interrupt flags are set to "1" depending on the corresponding interrupt factors.
The CPU operation is interrupted when any of the conditions below set an interrupt factor flag to "1".
The corresponding mask register is "1" (enabled)
The interrupt flag is "1" (EI)
The interrupt factor flag is a read-only register, but can be reset to "0" when the register data is read out.
At initial reset, the interrupt factor flags are reset to "0".
Note: Read the interrupt factor flags only in the DI status (interrupt flag = "0"). A malfunction could result
from read-out during the EI status (interrupt flag = "1").

4.16.2 Specific masks and factor flags for interrupt
The interrupt factor flags can be masked by the corresponding interrupt mask registers.
The interrupt mask registers are read/write registers. They are enabled (interrupt authorized) when "1" is
written to them, and masked (interrupt inhibited) when "0" is written to them.
At initial reset, the interrupt mask register is set to "0".
Table 4.16.2.1 shows the correspondence between interrupt mask registers and interrupt factor flags.
