Hi,
I have problems in reading the internal registers of Real Time Clock of the
PC. It seems like I am stack after the read.
Any suggestions (Code)
Thanks,
Benny

Documentation on this chip is available from INTEL in their MICROPROCESSOR AND PERHPHERIAL HANDBOOK, VOLUME 1. The real time clock found on the IBM AT and its successors is actually a combinatiion real time clock/calendar/non-volitile RAM chip made by Motorola -- I don't have the part number handy. The registers are documented in IBM's manual, IBM AT TECHNICAL REFERENCE HARDWARE MANUAL.
