在MHC設定smarteeprom size的地方,這個說明看不出哪一欄要設定什麼東西吧...?
MHC

查了datasheet,看到下面的說明:
DataSheet
The SBLK bits indicate the number of blocks allocated per SmartEEPROM virtual sector.

The SmartEEPROM virtual page size (PSZ bits). This configuration is loaded after a reset into
SEESTAT.PSZ bits.

看起來MHC的兩欄指的是SEESTAT.PSZ(上欄) 與SEESTAT.SBLK(下)?
然後SEESTAT.SBLK選0表示4,選1表示8,...,是這樣?

DataSheet那張圖應該要怎麼解釋?
以範例中的1,3為例的話,表示有1個page,1個sector有32個block,此時SmartEEPROM size為4096(Bytes)?
這裡面的page、sector及block間是什麼關係?怎麼組合出4096這個size的?

MHC的NVMCTRL裡好像沒有SmartEEPROM 的enable選項,所以這是個預設開啟的功能,不想使用的話就把SEESTAT.PSZ與SEESTAT.SBLK都設成0,是這個意思嗎?
