The sensor board used 100k pullup resistors on SDA, SCL, and WP. Checking the spec sheet on the chip, I found "typical" values of 10k for 100kHz, and 2k for 400kHz. It was no obvious why there was a pull-up resistor on WP because the chip has a pull-down resistor on that pin. Checking with TI, I found slaa115, which had 10 resistors on SDA and SCL. TI uses the trick of setting the output values low and then using DIR changes to switch polarity. It seemed to me that the 100k pullups might limit speed on an MSP430.
