10.2.2
10.2.2.1
The Boundary-Scan register consists of a series of Boundary-Scan cells arranged to form a scan path around the
boundary of the ZL50062/64 core logic.
10.2.2.2
The Bypass register is a single stage shift register to provide a one-bit path from TDi to TDo.

10.3
A Boundary Scan Description Language (BSDL) file is available from Zarlink Semiconductor to aid in the use of the
IEEE 1149.1 test interface.
11.0
When the most significant bit, A14, of the address bus is set to ’1’, the microprocessor performs an access to one of
the device’s internal memories. The Control Register bits MS[2:0] indicate which memory (Local Connection, Local
Data, Backplane Connection, or Backplane Data) is being accessed. Address bits A0-A13 indicate which location
within the particular memory is being accessed.
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.

Selects memory or register access (0 = register, 1 = memory).
Note that which memory (Local Connection, Local Data, Backplane Connection, Backplane
Data) is accessed depends on the MS[2:0] bits in the Control Register.
