4.13.5 Programming notes
(1) The interrupt factor flags are set when the interrupt condition is established, even if the interrupt
mask registers are set to "0".
(2) After an interrupt occurs, the same interrupt will occur again if the interrupt enabled state (I flag =
"1") is set or the RETI instruction is executed unless the interrupt factor flag is reset. Therefore, be sure
to reset (write "1" to) the interrupt factor flag in the interrupt service routine before shifting to the
interrupt enabled state.
(3) After an initial reset, all the interrupts including NMI are masked until both the stack pointers SP1
and SP2 are set with the software. Be sure to set the SP1 and SP2 in the initialize routine. Further,
when re-setting the stack pointer, the SP1 and SP2 must be set as a pair. When one of them is set, all
the interrupts including NMI are masked and interrupts cannot be accepted until the other one is set.
