MC68HC908KX8 • MC68HC908KX2 • MC68HC08KX8 Data Sheet, Rev. 2.1
150 Freescale Semiconductor
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
13.7.2.2 Interrupt Status Register 2
IF14–IF11 — Interrupt Flags 14–11
These flags indicate the presence of interrupt requests from the sources shown in Table 13-2.
1 = Interrupt request present
0 = No interrupt request present
IF10–IF7 — Interrupt Flags 10–7
Since the MC68HC908KX8 parts do not use these interrupt flags, these bits will always read 0.
13.7.2.3 Interrupt Status Register 3
IF22–IF17 — Interrupt Flags 22–17
Since the MC68HC908KX8 parts do not use these interrupt flags, these bits will always read 0.
IF16–IF15 — Interrupt Flags 16–15
These flags indicate the presence of interrupt requests from the sources shown in Table 13-2.
1 = Interrupt request present
0 = No interrupt request present
