Are there any Atmel documents that have detailed I/O port timing for the AT90S2313? Specifically, what are the input port setup and hold times relative to XTAL1, XTAL1 to valid port output min and max, and sync and latency delays for the different modes?

Normally I use a 10ms power on reset (RC chain) locked to RST pin, it works fine... Have you using watch dog resets in you application?
