CPU Connection Example <Parallel Interface>
This section presents examples of the connection of this IC to a CPU.
Note that care is required with respect to read timing, since the time required to read a register, and the time required to
read a post-correction data packet (22 bytes) are different.
Normal connection
When hardware waits are applied to the
CPU, the wait time (RDY width)
requires care.
BUSWD = low: 8 bits
BUSWD = high: 16 bits
No. 6871-19/29

DMA transfer mode
I/O read/write operations are used for
the normal register read and write
operations. However, programmable
wait states may need to be inserted,
depending on the execution speeds.
DMA processing is only used for
readout of post-correction data.
Applications can select whether RD or
DACK is used as the DMA read control
signal by setting a register.
The default is to use the RD signal.
The data bus width in DMA mode is
always 8 bits.
CPU DMA mode setting example (For
reference only)
SH Series: Transfer type: 2-cycle
transfer
Transfer mode: Single
transfer mode
V Series:
Address mode: Dual
address mode
Bus mode: Cycle
stealing mode
The source side (the FM multiplex IC)
address is fixed at 0.
