ADuC703x: What is the minimum width of an external Reset Pulse?

Question

Hi all. 
 I was looking for a specification of the minimum pulse width of the external reset of　ADuC7036 and ADuC7039. 
 However, I could not find. 
 What is the minimum width of an external Reset Pulse? 
 Best Regards aimPoint.

The minimum RESET is related to the selected core clock. 
 As this can be down to 160kHz, it is recommended to have a reset-pulse-width of at least 2 clock-cycles - which is 12.5µs to be synchronized with the core.
