Zarlink Semiconductor Inc.
4.5 System Function Interface
All System Function Interface signals are 5 V tolerant.
The core of the chip will be held in reset for 16383 SYSTEM_CLK cycles after SYSTEM_RST has gone HIGH to
allow the PLL’s to lock.
4.6 Test Facilities
4.6.1 Administration, Control and Test Interface
All Administration, Control and Test Interface signals are 5 V tolerant.

Description
SYSTEM_CLK
I
W13
System Clock Input. The system clock
frequency is 100 MHz. The frequency
must be accurate to within ±32 ppm in
synchronous mode.
SYSTEM_RST
I
AA12
System Reset Input. Active low. The
system reset is asynchronous, and
causes all registers within the /1/4 to be
reset to their default state.
SYSTEM_DEBUG

AA11
System Debug Enable. This is an
asynchronous
