Figure 6-17. Interrupt Status Register 1 (INT1)
IF5–IF1 — Interrupt Flags 5, 4, 3, 2, and 1
These flags indicate the presence of interrupt requests from the
sources shown in Table 6-2.
1 = Interrupt request present
0 = No interrupt request present
IF6 — Interrupt Flag 6
Since the MC68HC908KX8 parts do not use this interrupt flag, this bit
will always read 0.
Bit 0 and Bit 1 — Always read 0
