Salam,

I have no idea about DS1558
But if you search the net (By Google) you will find source codes for DS1302 RTC.

I don't know why you want to use such device, there are simpler devices to work with PIC (DS1302, 3-wire and DS1307, i2c bus). Never the less you can access the RTC by addressing the the top 16 RAM locations. The RTC will keep watching the A0-A18 signal lines.
