AIS_IES
This bit selects the transition edge of the LAIS_S bit (b6,
STAT1,...) and the SAIS_S bit (b7,
STAT1,...).0: A transition from ‘0’ to ‘1’ on the LAIS_S bit (b6,
STAT1,...) / the SAIS_S bit (b7,
STAT1,...) will set the LAIS_IS bit (b6,
INTS1,...) / the SAIS_IS bit (b7,
INTS1,...) to ‘1’ respectively. (default)
1: Any transition from ‘0’ to ‘1’ or from ‘1’ to ‘0’ on the LAIS_S bit (b6,
STAT1,...) / the SAIS_S bit (b7,
STAT1,...) will set the

This bit selects the transition edge of the PA_S bit (b5,
STAT1,...).
0: A transition from ‘0’ to ‘1’ on the PA_S bit (b5,
STAT1,...) will set the PA_IS bit (b5,
INTS1,...) to ‘1’. (default)
1: Any transition from ‘0’ to ‘1’ or from ‘1’ to ‘0’ on the PA_S bit (b5,
STAT1,...) will set the PA_IS bit (b5,
INTS1,...) to ‘1’.
4
TOC_IES
This bit selects the transition edge of the TOC_S bit (b4,
STAT0,...).0: A transition from ‘0’ to ‘1’ on the TOC_S bit (b4,
STAT0,...) will set the TOC_IS bit (b4,
INTS0,...) to ‘1’. (default)
1: Any transition from ‘0’ to ‘1’ or from ‘1’ to ‘0’ on the TOC_S bit (b4,
STAT0,...) will set the TOC_IS bit (b4,
INTS0,...) to ‘1’.
3
TCKLOS_IES This bit selects the transition edge of the TCKLOS_S bit (b3,
STAT0,...).0: A transition from ‘0’ to ‘1’ on the TCKLOS_S bit (b3,

INTS0,...) to ‘1’. (default)
1: Any transition from ‘0’ to ‘1’ or from ‘1’ to ‘0’ on the TCKLOS_S bit (b3,
STAT0,...) will set the TCKLOS_IS bit (b3,
INTS0,...) to
‘1’.
2
TLOS_IES
This bit selects the transition edge of the TLOS_S bit (b2,
STAT0,...).
0: A transition from ‘0’ to ‘1’ on the TLOS_S bit (b2,
STAT0,...) will set the TLOS_IS bit (b2,
INTS0,...) to ‘1’. (default)
1: Any transition from ‘0’ to ‘1’ or from ‘1’ to ‘0’ on the TLOS_S bit (b2,
STAT0,...) will set the TLOS_IS bit (b2,
INTS0,...) to ‘1’.

LOS_IES
This bit selects the transition edge of the LLOS_S bit (b0,
STAT0,...) and the SLOS_S bit (b1,
STAT0,...).
0: A transition from ‘0’ to ‘1’ on the LLOS_S bit (b0,
STAT0,...) / the SLOS_S bit (b1,
STAT0,...) will set the LLOS_IS bit (b0,
INTS0,...) / the SLOS_IS bit (b1,
INTS0,...) to ‘1’ respectively. (default)

IB_IES
This bit selects the transition edge of the IBA_S bit (b1,
STAT1,...) and the IBD_S bit (b0,
STAT1,...).
0: A transition from ‘0’ to ‘1’ on the IBA_S bit (b1,
STAT1,...) / the IBD_S bit (b0,
STAT1,...) will set the IBA_IS bit (b1,
INTS1,...) /
