These bits may be used by other modules. See device-specific datasheet.
NMIIFG
Bit 4
NMI interrupt flag. NMIIFG must be reset by software. Because other bits in
IFG1 may be used for other modules, it is recommended to clear NMIIFG by
using
BIS.B
or
BIC.B
instructions, rather than
MOV.B
or
CLR.B
instructions.

Bits

These bits may be used by other modules. See device-specific datasheet.
WDTIFG
Bit 0
Watchdog timer interrupt flag. In watchdog mode, WDTIFG remains set until
reset by software. In interval mode, WDTIFG is reset automatically by
servicing the interrupt, or can be reset by software. Because other bits in IFG1
may be used for other modules, it is recommended to clear WDTIFG by using
BIS.B
or
BIC.B
instructions, rather than
MOV.B
or
CLR.B
instructions.
