Peripheral Security - ST STM32MP13-ETZPC Manual

• Secure resources:
• Not controlled by ETZPC
• ETZPC : write secure only
• TZC, AXIM/GPC, MDMA config, DMA3 config : always secure
• Non secure resources:
• Several peripherals are not concerned by security, they are not controlled by ETZPC
• Securable resources:
• Some peripherals can be either secure, write secure or non-secure according to DECPROT bits
• SYSRAM and BootROM memories have programmable secure region size according to
TZMA0/1 settings
Secure resources are not controlled from the ETZPC
The ETZPC itself is always write secure.
The TZC, the AXIM/GPC and the MDMA and DMA3
configuration ports are always secure.
Many peripherals are always non-secure, and are not
controlled by the ETZPC
Securable peripherals can be either secure, write secure or
non secure according to the DECPROT bits in the ETZPC
SYSRAM and BootROM memories have programmable
