9.2.2 Framer Register Bit Map
Table 9-7 contains the framer registers of the DS26521. Some registers have dual functionality based on the
selection of T1/J1 or E1 operating mode in the
RMMR and TMMR registers. These dual-function registers are
shown below using two lines of text. The first line of text is the bit functionality for T1/J1 mode. The second line is
the bit functionality in E1 mode, in italics. Bits that are not used for an operating mode are noted with a dash “—“.
When there is only one set of bit definitions listed for a register, the bit functionality does not change with respect to
the selection of T1/J1 or E1 mode. All registers not listed are reserved and should be initialized with a value of 00h
for proper operation.
