MCF548x Integrated Microprocessor Hardware Specifications
MOTOROLA
PRELIMINARY—SUBJECT TO CHANGE WITHOUT NOTICE
Signal Description
For burst-inhibited transfers, TSIZ[1:0] changes with each TS assertion to reflect the next transfer size. For
transfers to port sizes smaller than the transfer size, TSIZ[1:0] indicates the size of the entire transfer on the
first access and the size of the current port transfer on subsequent transfers. For example, for a longword
write to an 8-bit port, TSIZ[1:0] = 2’b00 for the first transaction and 2’b01 for the next three transactions.
If bursting is used and in the case of longword write to an 8-bit port, TSIZ[1:0] is driven to 2’b00 for the
entire transfer.
1.5.1.1.7
Byte Selects (BE/BWE[3:0])
The four byte enables are multiplexed with the byte-write-enable signals. Each pin can be individually
programmed through the chip select control registers (CSCRs). For each chip select, assertion of byte
enables for reads and byte-write enables for write cycles can be programmed. Alternatively, users can
program byte-write enables to assert on writes and no byte enable assertion for read transfers.
The byte strobe (BE/BWE[3:0]) outputs indicate that data is to be latched or driven onto a byte of the data.
BE/BWE[3:0] signals are asserted only to the memory bytes used during a read or write access.
1.5.1.1.8
Output Enable (OE)
The output enable signal is sent to the interfacing memory and/or peripheral to enable a read transfer. OE is
asserted only when a chip select matches the current address decode.
1.5.1.1.9
Transfer Acknowledge (TA)
The external system drives this input to terminate the bus transfer. For write cycles, the processor continues
to drive data at least one clock after FBCSx is negated. During read cycles, the peripheral must continue to
drive data until TA is recognized. The number of wait states is determined either by an internally
programmed auto acknowledgement or the external TA input. If the external TA is used, the peripheral has
total control over the number of wait states.
1.5.1.2
SDRAM Controller Signals
These signals are used for SDRAM accesses.
1.5.1.2.1
SDRAM Data Bus (SDDATA[31:0])
SDDATA[31:0] is the bidirectional, non-multiplexed data bus used for SDRAM accesses. Data is sampled
by the MCF548x on the rising edge of SDCLK when in SDR mode, and on both the rising and falling edge
of SDCLK when in DDR mode.
1.5.1.2.2
SDRAM Address Bus (SDADDR[12:0])
The SDADDR[12:0] signals are the 13-bit address bus used for multiplexed row and column addresses
during SDRAM bus cycles. The address multiplexing supports up to 256 Mbits of SDRAM per chip select.
1.5.1.2.3
SDRAM Bank Addresses (SDBA[1:0])
Each SDRAM module has four internal row banks. The SDBA[1:0] signals are used to select the row bank.
It is also used to select the SDRAM internal mode register during power-up initialization.
