Hi,

The data is not the time. The byte is 0x73 when I read the second. The bits are not the time format. So I think that the data is not time. I have supplied the vcc with 3.3v. What would I do next?

This is the nature of the problem. We can read all twenty registers, however, the values internal to the registers do not change. Currently, we hooked up the following pins: NF to ground, Vss to Ground, VBAT to 3V, SDI and SDO to respective SPI inputs and outputs, SCL to SPI clock, and Enable to chip select, as well as Vcc to +3.3V. No other pins are connected.

Our main questions are these: 1. Is there any other pins that needs to be hooked up for the M41ST95 to work? 2. Is there any initialization code that is necessary?

Thanks.
