6. REGISTERS
The framers are memory-mapped as follows:
DS31412 has 12 framers and uses address space 000h to BFFh. DS3148 has eight framers and uses address
space 000h to 7FFh. DS3146 has six framers and uses address space 000h to 5FFh. DS3146 does not have
address pin A[11].
Table 6-A
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
registers are mapped into addresses 06h and 07h 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.
