2.9.3.2 Packet Copy in SRAM

Some packets initially stored during the Manufacturing Final Test in the OTP engineering area are made available for the user application in the SRAM.

When the ROM code launches a bootstrap or executes the SAM-BA Monitor, the packets are copied into the SRAM0 at address 0x00111CF0.

When the OTPC emulation mode is still allowed, those packets are copied as well into the SECURAM, making them available directly using OTPC packet read in emulation.

The user can choose to store them definitively into the real OTP User Area, preventing further usage of OTPC emulation mode, and disable the copy by the ROM code by writing the word ENG_PKT_COPY_DIS in the Boot Configuration Packet.
