Lizard provides several different resets signals. Please refer to Reset scheme for more details.

Memory organization[edit | edit source]

Lizard memory organizaton is detailed here.

I2C busses and peripherals[edit | edit source]

Please refer to this page for more details.

CAN interfaces[edit | edit source]

Please refer to this page for more details.

Power consumption[edit | edit source]

Please refer to this page for more details.

Boot sequence[edit | edit source]

By default, Lizard tries to load boot code (boot sequence) from the NOR flash.

For more informaton about boot sequence options please refer to Boot sequence.

Integration guide[edit | edit source]
