LC60: LVD Status at POR and 1.8V Discrepancy

Hi,
 
LVD is activated automatically at any reset. And configured for "Force an MCU reset when LVDF = 1."
 
Low-voltage detection threshold — low range VLVDL: (LC60 datasheet, page 326)
                min    typ   max
(VDD falling)   1.76   1.8   1.88 V
(VDD rising)    1.93   1.98  2.04 V
 
If so, how can we expect MCU works at 1.8V properly?
With these values, minimum MCU working voltage should be 2.04V?
 
Regards,
BP.
