SFDT
Mailbox register for interfacing with flash memory block. (Data register)
Symbol
Function
SFST
This is a read-only register. The read-back value is indexed by SFST_SEL in the
SuperFlash Configuration Register (SFCF)
SFST_SEL=
0H: Manufacturer’s ID
1H: Device ID0 = F7H
2H: Device ID1 = Device ID (Refer to Table 11 on page 32)
3H: Boot Vector
4H: Page-Security bit setting
5H: Chip-Level Security bit setting and Boot Options
