49 / 88 page  XRT83SL38 47 REV. 1.0.2 OCTAL T1/E1/J1 SH TRANSCEIVER WITH CLOCK RECOVERY AND JITTER ATTENUATOR MICROPROCESSOR REGISTER TABLES The microprocessor interface consists of 256 addressable locations. Each channel uses 16 dedicated 8 byte registers for independent programming and control. There are four additional registers for global control of all channels and two registers for device identification and revision numbers. The remaining registers are for factory test and future expansion. The control register map and the function of the individual bits are summarized in Table 17 and Table 18 respectively.
