I made an project with HCS08GT32 using the Processor Expert Bean Time/Date
an RTC bean. I feed the MCU with an 32.768Khz X-tal.
i put a 10Meg resistor and 2pcs 12pf cap in the osc circuit according to recommendations.
The problem is that the RTC is running to fast approx 38Seconds / 24Hour.
I changed the X-tal to other manufactures with same result.
How to trim the RTC to an lower error?
