Description

GTZC1 SRAM1 MPCBB control register

Fields

GLOCK

lock the control register of the MPCBB until next reset This bit is cleared by default and once set, it can not be reset until system reset.

0 (B_0x0): control register not locked

1 (B_0x1): control register locked

INVSECSTATE

SRAMx clocks security state This bit is used to define the internal SRAMs clocks control in RCC as secure or not.

0 (B_0x0): SRAMs clocks are secure if a secure area exists in the MPCBB. It is non secure if there is no secure area.

1 (B_0x1): SRAMs clocks are non-secure even if a secure area exists in the MPCBB, and secure even if no secure block is set in the MPCBB.

SRWILADIS

secure read/write illegal access disable This bit disables the detection of an illegal access when a secure read/write transaction access a non-secure blocks of the block-based SRAM (secure fetch on non-secure block is always considered illegal).

0 (B_0x0): enabled, secure read/write access not allowed on non-secure SRAM block

1 (B_0x1): disabled, secure read/write access allowed on non-secure SRAM block
