7.3 Master/slave system configuration example
The following is an example of a system with master and slave functions.
(1) Coprocessor only configuration
_
__________
The slave M32000D3FP accesses only the internal DRAM and never the external bus. M/S and HREQ are
fixed at the "L" level.
The slave M32000D3FP executes the instructions that the master M32000D3FP downloads to the internal
DRAM. The data transfer request (processing complete) from the slave M32000D3FP is notified to the
master M32000D3FP by inputting the interrupt request via the programmable I/O port. The data transaction
is carried out when the master M32000D3FP accesses the internal DRAM in the slave M32000D3FP.
