Test Data Registers
11.2.2.1
The Boundary-Scan Register
The Boundary-Scan register consists of a series of Boundary-Scan cells arranged to form a scan path around the
boundary of the MT90869 core logic.
11.2.2.2
The Bypass Register
The Bypass register is a single stage shift register to provide a one-bit path from
TDi
to
TDo
.
11.2.2.3

Boundary Scan Description Language (BSDL) File
A Boundary Scan Description Language (BSDL) file is available from Zarlink Semiconductor to aid in the use of the
IEEE 1149.1 test interface.

Memory Address Mappings
Table 8 - Address Map for Data and Connection Memory Locations (A14=1)
The device contains two data memory blocks, one for received backplane data and one for received local data. For
all data rates the received data is converted to parallel format by internal serial to parallel converters and stored
sequentially in the relevant data memory.
12.1
Backplane Data Memory Bit Definition
The 8-bit Backplane Data Memory (BDM) has 8,192 positions. The locations are associated with the backplane
input streams and channels. The address bits (A13:0) of the microprocessor define the addresses of the streams
and the channels. The BDM is configured as follows:
Address Bit
Description
A14
Selects memory or register access
A13-A9
Stream address (0-31)
A8-A0
Channel address (0-511)
Notes:
1. Bit A14 must be high for accessing to data and connection memory positions. Bit A14 must
be low for accessing registers.
2. Streams 0 to 15 are used when the backplane serial streams are at 32.768Mb/s.
3. Channels 0 to 31 are used when serial stream is at 2.048Mb/s.
4. Channels 0 to 63 are used when serial stream is at 4.096Mb/s.
5. Channels 0 to 127 are used when serial stream is at 8.192Mb/s.
6. Channels 0 to 255 are used when serial stream is at 16.384Mb/s.
7. Channels 0 to 511 are used when serial stream is at 32.768Mb/s.
