vt_uncferr_ptr:
This field points to which of the unmasked uncorrectable errors happened
first. This field is only valid when the corresponding error is unmasked and
the status bit is set and this field is rearmed to load again when the status bit
indicated to by this pointer is cleared by software from 1 to 0.
Value of 0x0 corresponds to bit 0 in VTUNCERRSTS register, value of 0x1
corresponds to bit 1 and so forth.
