19.3.3 Host to Client Access
The following table shows how hosts and clients interconnect. Writing in a register or field not dedicated to a host or a client has no effect.
| HOST | |||||||||||||

Note:
-
To avoid deadlock when accessing the AESB client, the QSPI0, QSPI1 and DDR2 Port 0 client Configuration registers (MATRIX_SCFGx) must be configured either with DEFMSTR_TYPE = NONE ('0') or with DEFMSTR_TYPE = FIXED ('2') and FIXED_DEFMSTR = 10.
