Discrepancy/Bug with LVDSPLL_TST register in VDC5 sample

I'm trying to adapt the VDC5 sample to our custom hardware and have discovered a discrepancy between the RZ User's Manual and the sample code.

In Section 40 (p.40-5) of the User's Manual, the 6-bit field LVDSPLL_TST in the LCLKSELR register is supposed to be set to "010000" (or 0x10).  However, in the VDC5 sample, in the lcd_setttings.c source file, this field is defined as "(8u)".

Is this a bug?  If so, will it make any difference?

In other words: Who should I trust more?  The sample code or the User's Manual?

Thanks.
