19.3.2 Matrix Clients

The H64MX manages 15 clients. Each client has its own arbiter providing a dedicated arbitration per client.

14	AESB	Not applicable

Note:

For each SDMMCx, see Security Types of SDMMC System Bus Clients for Internal Securable to Peripheral type configuration. A consistent configuration must be done for:
- the client port,
- MATRIX_SPSELSR for the general interrupt and the host port,
- MATRIX_SPSELSR for the TIMER interrupt.
For consistency, each DDR2 port must have the same TrustZone access management configuration.
