I2C commands with DS1388 RTC

I realize that there is a lot on this forum about I2C and I have done a fair bit of reading, but I'm having some trouble using the I2C commands with a BS2px to control the DS1388 RTC from Maxim. It is similar to the DS1307, which does have some good code written for it without using the I2C commands, but I can't understand how to use the I2C commands I2CIN and I2COUT in this context. After the slave address there is an interval address, but in addition with the DS1388 there is a block and a word address. Do I need to send both to the device? and do I need to append them together or send them separately?

    You could have a look at this example program for a 1307 and bsp that might give you some idea.

    thank you. I realize the problem is that i wired the two lines SDA and SCL backwards. Unfortunately I don't see a way to re-configure the I2C commands for this reversal.

    thanks again
