17.2 MCF5307 Bus Signals
The bus signals provide the external bus interface to the MCF5307.
17.2.1 Address Bus
The address bus provides the address of the byte or most-significant byte (MSB) of the
word or longword being transferred. The address lines also serve as the DRAM addressing,
providing multiplexed row and column address signals. When an external device has
ownership of the MCF5307 bus, the device must drive the address bus and assert TS or AS
to indicate the start of a bus cycle. During an interrupt acknowledge access, A[4:2] indicate
the interrupt level being acknowledged.
17.2.1.1 Address Bus (A[23:0])
The lower 24 bits of the address bus become valid when TS is asserted. A[4:2] indicate the
interrupt level during interrupt acknowledge cycles.
17.2.1.2 Address Bus (A[31:24]/PP[15:8])
These multiplexed pins can serve as the most-significant byte of the address bus, or as the
most-significant byte of the parallel port. Programming the PAR in the system integration
module (SIM) determines the function of each of these eight multiplexed pins. These pins
are programmable on a bit-by-bit basis.
