5.3.5 IE1, Interrupt Enable Register 1

7 6 5 4 3 2 1 0

OFIE

(1)

rw-0

Bits 7-2 These bits may be used by other modules. See device-specific data sheet.

OFIE Bit 1 Oscillator fault interrupt enable. This bit enables the OFIFG interrupt. Because other bits in IE1 may be used

for other modules, it is recommended to set or clear this bit using BIS.B or BIC.B instructions, rather than

MOV.B or CLR.B instructions.

0 Interrupt not enabled

1 Interrupt enabled

Bits 0 This bit may be used by other modules. See device-specific data sheet.

(1)

MSP430G22x0: This bit should not be set.

5.3.6 IFG1, Interrupt Flag Register 1

7 6 5 4 3 2 1 0

OFIFG

(1)

rw-1

Bits 7-2 These bits may be used by other modules. See device-specific data sheet.

OFIFG Bit 1 Oscillator fault interrupt flag. Because other bits in IFG1 may be used for other modules, it is recommended to

set or clear this bit using BIS.B or BIC.B instructions, rather than MOV.B or CLR.B instructions.

0 No interrupt pending

1 Interrupt pending

Bits 0 This bit may be used by other modules. See device-specific data sheet.

(1)

MSP430G22x0: The LFXT1 oscillator pins are not available in this device. The oscillator fault flag will always be set by hardware. The

interrupt enable bit should not be set.
