Selecting the Code Fetch Source
SEC1212-DEV can execute code from Internal /OTP ROM as well as from external
serial SPI flash (one at a time).
The following sub-sections detail the pre-requisites to select the required code fetch
source.
2.5.7.1
CODE EXECUTION FROM INTERNAL BOOT ROM
1. OTP_ROM_EN & FORCE_OTP_ROM bits are not programmed through OTP
Programmer application
2. Pins 2-3 of J38 are to be shorted
2.5.7.2
CODE EXECUTION FROM INTERNAL OTP ROM
1. OTP should have been programmed through OTP Programmer application
2. OTP_ROM_EN bit is programmed through OTP Programmer application
3. Pins 2-3 of J38 are to be shorted
2.5.7.3
CODE EXECUTION FROM SPI FLASH
1. SPI Flash should have been programmed through SPI Flashwriter application
2. FORCE_OTP_ROM bit is not programmed through OTP Programmer applica-
tion
3. Pins 1-2 of J38 are to be shorted
