CLKIN
The value of the R/W signal that controls the data direction of the bus interface
cannot be changed during CS="L". Hold this value while CS="L".
Also, where marked above with V, 3 to 7 CLKIN clock periods are necessary for
the first read operation (also when reading crosses an 128-bit boundary) when
reading from the internal DRAM. Hold the input value of the address or other control
signals during these wait cycle periods (DC = "H"). Consecutive read operations
within an 128-bit boundary are completed in 1 CLKIN clock period.
During these wait cycle period, CS cannot be returned to an "H" level (the access
cannot be aborted). CS can only be returned to an "H" level after DC is driven to "L".
When the M32000D3FP is in the hold state and an "L" level is input
__
to CS, the M32000D3FP interprets it as a bus access request to the
__
internal DRAM. In this case, when the R/W signal is an "H" level, the
memory controller drives a read cycle to the internal DRAM. In the
read cycle, the 16-bit data for the address specified with A8 to A30,
____
___
is output from D0 to D15 regardless of the BCH and BCL settings.
__
Also the DC signal is output.
The M32000D3FP reads 128 bits of data from the block on the 128-
bit boundary including the requested address into the 128-bit buffer
of the bus interface unit. 3 to 7 CLKIN clock periods are necessary
for the first bus access, however, when reading consecutive address
within the 128-bit boundary, the subsequent read bus cycles are com-
pleted in 1 CLKIN clock period because a read from the internal DRAM
__
does not take place. After DC outputs an "L" level (access complete),
__
return CS to the "H" level between the CLKIN falling edge corre-
sponding to the last read cycle and the following CLKIN falling edge.
______
Return HREQ to the "H" level to return the M32000D3FP to the nor-
mal operation mode from the hold state either at the same time as or
__
after CS is returned to the "H" level.
