TFRA08C13 OCTAL T1/E1 Framer
Microprocessor Interface
(continued)
Microprocessor Interface Register Address Map
The register address space is divided into thirteen (13) contiguous banks of 512 addressable units each. Each
addressable unit is an 8-bit register. These register banks are labeled as REGBANK[0—12]. The register address
map table gives the address range of these register banks and their associated circuit blocks. REGBANK0 contains
the global registers which are common to all the circuit blocks on the TFRA08C13. REGBANK[1—8] are attached
to the framer circuit blocks. REGBANK[9—12] are attached to the FDL circuit blocks. The descriptions of the indi-
vidual register banks can be found in the appropriate sections of this document. In these descriptions, all
addresses are given in hexadecimal.
Addresses out of the range specified by Table 54 must not be
addressed. If they are written, they must be written to 0. An inadvertent write to an out-of-range address
may be corrected by a device reset.
Table 54. TFRA08C13 Register Address Map
* Core registers are common to all circuit blocks on the TFRA08C13.
I/O Timing
*
The I/O timing specifications for the microprocessor interface are given in Table 55. The microprocessor interface
pins are compatible with CMOS/TTL I/O levels. All outputs, except the data bus D[7:0], are rated for a capacitive
load of 50 pF. The D[7:0] outputs are rated for a 100 pF load.
* See Product Advisory AY99-041 or more information.
