Anyone, I'm trying to get the real time clock working on a 5509a I use the code directly from TI's RTC appnote (spra384a). But alway read back 0 from all RTC registers? If I look at the RTC memory locations (0x1800) I get an error reading from location 0x3000 ( my wording may be a bit off). My first guess is that my I/O GEL mapping was wrong, but it looks fine. I can dump memory locations to 0x17ff, and then I get the error? Anyone seen this type of thing happen? Thanks for any ideas Peejayblack |
