Description

GTZC1 TZSC memory 3 sub-region A watermark register

Fields

SUBA_START

Start of sub-region A in region x This field defines the address offset of the sub-region A, to be multiplied by the granularity defined in Table30, versus the start of the region x. External memories that are watermark controlled, start fully non-secure at reset when TZEN=0xC3. When TZEN=0xB4, external memories start fully secure (inverted reset value).

SUBA_LENGTH

Length of sub-region A in region x This field defines the length of the sub-region A, to be multiplied by the granularity defined in Table30. When SUBA_START + SUBA_LENGTH is higher than the maximum size allowed for the memory, a saturation of SUBA_LENGTH is applied automatically. If SUBA_LENGTH = 0, the sub-region A is disabled.(SREN bit in GTZC1_TZSC_MPCMWxACFGR is cleared).
