pins. If RSCFS does not exist, the time slot offset is between RSFSn and the start of the Basic Frame output on RSDn & RSSIGn. In Receive Multi-
plexed mode, each framer contributes every fourth time slot on MRSD[1:2] and MRSSIG[1:2].

Type
These bits determine the time slot offset between the signal on the RSCFS pin and the start of the Basic Frame output on the RSDn & RSSIGn
They define a binary number. The offset can be set from 0 to 127 time slots.
Valid when the CMS (b2, E1-010H) is logic 1 and the DE (b4, E1-010H) is not equal to the FE (b3, E1-010H).
= 0: The second active edge of RSCCK is used to update the signal on the RSDn, RSSIGn and RSFSn pins, or the first active edge of MRSCCK
= 1: The first active edge of RSCCK is used to update the signal on the RSDn, RSSIGn and RSFSn pins, or the second active edge of MRSCCK
(The signal on the RSCFS/MRSCFS pin is always sampled on the first active edge.)
In Receive Multiplexed mode, the RSD_RSCFS_EDGE in all eight framers should be set to the same value.
When the CMS (b2, E1-010H) is logic 1 and the DE (b4, E1-010H) is equal to FE (b3, E1-010H), the signals on the RSDn/MRSD, RSSIGn/MRS-
Valid when the CMS (b2, E1-010H) is logic 0.
= 0: Disable the bit offset.
= 1: Enable the bit offset.
Valid when the CMS (b2, E1-010H) is logic 0 and the BOFF_EN is logic 1.
These bits define a binary number. The content in the BOFF[2:0] determines the bit offset between the signal on the RSCFS pin and the start of
Programming of the Bit Offsets is consistent with the convention established by the Concentration Highway Interface (CHI) specification. Refer to
