7.11.32 FSM Sector Register 1 (FSM_SECTOR1)
This is a banked register. A separate register is implemented for each bank, but they all occupy the same
address. The correct bank must be selected in the FMAC register before reading or writing this register.
See Section 7.11.16.

Bit Field Value Description
31-0 SECT_ERASED[31:0] Sectors Erased.
There is one bit for each sector. Bit 0 corresponds to sector 0, bit 1 corresponds to
sector 1, and so on.
0 During bank erase, each sector whose corresponding bit is 0 will be erased. After bank
erase, the bit corresponding to each sector that is erased will be changed from 0 to 1.
1 During bank erase, each sector whose corresponding bit is 1 will not be erased.
NOTE: If the bank has less than 32 sectors, only those many LSB bits of FSM_SECTOR1 are valid.
For EEPROM bank having more than 32 sectors, use this register in conjunction with
FSM_SECTOR2.
7.11.33 FSM Sector Register 2 (FSM_SECTOR2)
This register is applicable to EEPROM bank having more than 32 sectors only. Refer device datasheet to
find the number of EEPROM sectors in a particular device.

Bit Field Value Description
31-0 SECT_ERASED[63:32] Sectors Erased.
There is one bit for each sector. Bit 0 corresponds to sector 32, bit 1 corresponds to
sector 33, and so on.
0 During bank erase, each sector whose corresponding bit is 0 will be erased. After bank
erase, the bit corresponding to each sector that is erased will be changed from 0 to 1.
1 During bank erase, each sector whose corresponding bit is 1 will not be erased.
