BOFF[2:0] bits and the TSOFF[6:0] bits are not ‘0’ respectively.
the corresponding frame input on the TSDn/MTSDA(MTSDB) pin will
delay ‘N’ clock cycles to the framing pulse on the TSFSn/MTSFS pin.
(Here ‘N’ is defined by the BOFF[2:0] bits.) When the CMS bit is ‘0’ and
the TSOFF[6:0] bits are set, the start of the corresponding frame input
on the TSDn/MTSDA(MTSDB) pin will delay ‘8 x M’ clock cycles to the
framing pulse on the TSFSn/MTSFS pin. (Here ‘M’ is defined by the
TSOFF[6:0].)
BOFF[2:0] bits are set, the start of the corresponding frame input on the
TSDn/MTSDA(MTSDB) pin will delay ‘2 x N’ clock cycles to the framing
pulse on the TSFSn/MTSFS pin. (Here ‘N’ is defined by the BOFF[2:0]

channel offset can be configured from 0 to 127 channels (0 & 127 are
included).
