Post by thread:[SX] RTCC high or low

Anyway, should I tie that high (via a 10k resistor) or low to ground (via resistor?). I couldn't seem to find any examples in the three SX books (Beg Assm, SX-Key Dev Sys, Exploring SX/B). If anyone is looking for a huge list of CAD programs (some free, some not), Olimex (PCB mfg) seems to keep a pretty accurate list:

In case, you don't plan to ever externally clock the RTCC pin, it is fine to directly tie it to Vss (ground).
