Hi

Here is what the manual says about clock speed.  It defaults to 1.8432 MHz 
so your clock speed may be too slow to support the SPI speed to are using. 
You could switch to an external crystal or perhaps you have selected an 
external crystal and it is not there forcing it to return to default.


Manual Quote follows:
Clock - select clock source
The Clock command allows you to change the clock source. The clock source is 
stored in Flash memory as part of the device configuration bits. The clock 
selection indicates the clock source to use at power-up. If the selected 
clock source can't be validated at power-up, the uM-FPU V3.1 chip will 
default to an internal clock of 1.8425 MHz. The available clock speeds and 
clock sources are selected by entering one of the following values:

Value Clock Speed Clock Source
20 1.8425 MHz internal oscillator
E1 7.37 MHz internal oscillator
EA 14.74 MHz internal oscillator
E3 29.48 MHz internal oscillator
E5 10.0 MHz external 10.0 MHz crystal
E6 20.0 MHz external 10.0 MHz crystal
E7 29.4912 MHz external 7.3728 MHz crystal

Good Luck

Dave
