HTS221 over SPI, unable to write registers after soft reboot

Hi, I'm using the HTS221 with an STM32F205. The communication channel is SPI. I'm finding that when I reboot my processor without cycling power, once the processor is back up and running it is unable to write to any of the HTS221's control registers so I am unable to put it in active mode. I am running the SPI bus at ~1MHz.

Any advice/ideas would be greatly appreciated!

Thanks,
Doug
