F021 Level 2 Flash Module Controller (L2FMC)
7.5.2 OTP Memory
7.5.2.1 Flash Bank and Sector Sizes
Flash Bank/Sectoring information can be determined from the device-specific datasheet or can be
computed by reading locations in the TI OTP and L2FMC registers.
The number of banks, which banks are available, and the number of sectors for bank 0 can be read from
TI OTP location F008 0158h as shown in Figure 7-3 and described in Table 7-4.

8 B0 1 1 = Bank 0 is present
7-0 NUM_Banks 3 Number of banks on this part.
The bank sector information is repeated once for each bank in the device. The number of sectors is
unique for each bank. The number of banks and which banks are implemented is repeated in each
location. Use the TI OTP information for bank 0 to determine which banks are in the device, and then read
the number of sectors for each bank using the TI OTP locations shown in Table 7-5.
