Is there any restricts on SPI feature on Necleo L053R8?

I set the SPI on L053R8 works in slave mode. When the master's clock less than 800KHz, slaver can read/write data success. But when I change the master's clock to 1.6MHz, the L053R8 cannot read one byte any more which is correct, each byte is '0xFF'....

I would like to know about the 3 character date code, YWW. I understand the WW is week of the year, but with the year only being one character, does 8 refer to 2018 or 2008?

Looks like ST would have used at least 2 character for the year.Thanks
