11.2.2
11.2.2.1
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 is a single stage shift register to provide a one-bit path from TDi to TDo.

11.3
A Boundary Scan Description Language (BSDL) file is available from Zarlink Semiconductor to aid in the use of the
IEEE 1149.1 test interface.
12.0
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.

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 32.768 Mb/s.
3. Channels 0 to 31 are used when serial stream is at 2.048 Mb/s.
4. Channels 0 to 63 are used when serial stream is at 4.096 Mb/s.
5. Channels 0 to 127 are used when serial stream is at 8.192 Mb/s.
6. Channels 0 to 255 are used when serial stream is at 16.384 Mb/s.
7. Channels 0 to 511 are used when serial stream is at 32.768 Mb/s.
