#154124 - Changing the bit.... Responding to: ???'s previous message |
Well the most straightforward way is to read the register with the bit that must be changed to the ACC and then ....
- if you want to clear a bit in it use a CLR bit instruction - if you want to set the bit in it use the SETB bit instruction Write the resulting ACC content back to the register in the RTC. I presume since you have the RTC "working in 24 hour" mode that you have functioning RTC register level read and write routines in place that you can leverage for reading this control register at location 02h.
