10.2.2 Framer Register Bit Map
Table 10-8 contains the framer registers of the DS26518. 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 denoted with a single
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. The addresses shown are for Framer 1. Addresses for Framers 2 to 8 can be
calculated using the following formula: Address for Framer n = (Framer 1 address + (n - 1) x 200hex).
