These register bits are only valid for master slices. For slave slices, they should be ignored.
If the WCIMODE bit in the SPECTRA-9953 Master Reset and Configuration Register (Register
0000H) is set high, these interrupt status bits are cleared on a write of logic one. Otherwise,
these interrupt status bits are cleared on read.
OOFI
The out of frame interrupt status (OOFI) bit is an event indicator. OOFI is set to logic 1 to
indicate any change in the status of OOFV. The interrupt status bit is independent of the
interrupt enable bit. OOFI is cleared to logic 0 when this register is read or written as
described above.
LOFI
The loss of frame interrupt status (LOFI) bit is an event indicator. LOFI is set to logic 1 to
indicate any change in the status of LOFV. The interrupt status bit is independent of the
interrupt enable bit. LOFI is cleared to logic 0 when this register is read or written as
described above.
