describes SDRAM controller signals.
A10 precharge strobe. A precharge cycle occurs only after a page miss. During precharge, the SDRAM
writes the designated on-chip RAM page buffer back into the SDRAM array. Precharge latency is set
in SDTR[RP]. The reset value is 2 cycles, RP = 01.
For SDRAM devices, these outputs should be connected to individual DQM signals. During SDRAM
accesses, these signals indicate a byte transfer between SDRAM and the MCF5272 when asserted.
Note that most SDRAMs associate DQM3 with the MSB, in which case BS3 should be connected to
the SDRAM's DQM3 input, and so forth.
SDRAM column address strobe output
DRESETEN is asserted to indicate that the SDRAM controller is to be reset whenever RSTI asserts. If
DRESETEN is negated, RSTI does not affect the SDRAM controller, which continues to refresh
external memory. This is useful for debug situations where a reset of the device is required without
losing data located in SDRAM. DRESETEN is normally tied high or low depending on system
requirements. It should never be tied to RSTI or RSTO.
SDRAM row address strobe output
Fourteen address signals are multiplexed to form SDRAM_ADR[13:0], which are used for connecting
to SDRAM devices as large as 256 Mbits. SDRAM can be configured for 16- or 32-bit wide interface to
the MCF5272 data bus. For an SDRAM array with a 32-bit data bus, SDRAM address signals are
multiplexed starting with A2. For a 16-bit data bus, address signals are multiplexed starting with A1.
SDRAM controller bank address select outputs. Assigned to internal high-order address signals by
programming SDCR[BALOC]. This allows using SDRAM devices of different sizes without changing
the board layout. See
