DS3142 Datasheet, PDF (15/88 Pages) Dallas Semiconductor – Single/Dual/Triple/Quad DS3/E3 Framers

DS3141/DS3142/DS3143/DS3144 Single/Dual/Triple/Quad DS3/E3 Framers
6. REGISTERS
The framers are memory-mapped as follows:
Framer 1 (000h to 0FFh)
Framer 2 (100h to 1FFh)
Framer 3 (200h to 2FFh)
Framer 4 (300h to 3FFh)
The DS3141 uses address space 000h–0FFh and does not have address pins A[9:8]. The DS3142 uses address
space 000h–1FFh, and does not have address pin A[9]. The DS3143 has three framers and uses address space
000h–2FFh. The DS3143 ignores any writes to 300h–3FFh, and returns 00h for any reads from 300h–3FFh. The
DS3144 has four framers and uses address space 000h–3FFh.
Table 6-A shows the framer register map. Bits that are underlined are read-only bits. Bits that are marked “N/A” are
undefined. Addresses that are not listed in Table 6–A are undefined. Undefined registers and bits are reserved for
future enhancements and must always be written with logic 0 and ignored when read.
The device ID register is mapped into address 00h of every framer on the chip. Similarly, the ISR1 register is
mapped into addresses 06h of every framer on the chip. All other registers are unique to each framer, including the
reset (RST) register bit in MC1, which only resets the framer it is associated with, not the entire chip.
