Preliminary Data Sheet
64
AMCC Proprietary
Revision 1.26 – October 15, 2007
System Interface
SysClk
Main system clock input.
I
3.3 V tolerant
2.5V CMOS
1
SysErr
Set to 1 when a machine check is generated.
O
3.3 V tolerant
2.5V CMOS
SysReset
Main system reset. External logic can drive this bidirectional pin
low (minimum of 16 cycles) to initiate a system reset. A system
reset can also be initiated by software. Implemented as an open-
drain output (two states; 0 or open circuit).
