Interrupt Enable Flag (IE: $000, Bit 0):
The interrupt enable flag executes interrupt enable/disable for all
interrupt requests as listed in table 3. It is reset by interrupt processing and set by the RTNI instruction.

External Interrupt (
INT
0
):
INT
0
input should be selected by using port mode register B (PMRB: $024), so
that the external interrupt request flag (IF0) is set at the falling edge of the
INT
0
input.
External Interrupt Request Flag (IF0: $000, Bit 2):
The external interrupt request flag is set by the
INT
0
input edge, as listed in table 4.

External Interrupt Mask (IM0: $000, Bit 3):
IM0 is a bit which masks the interrupt request caused by an
external interrupt request flag, as listed in table 5.

Timer B Interrupt Request Flag (IFTB: $002, Bit 0):
The timer B interrupt request flag is set by the
overflow output of timer B, as listed in table 6.
