For More Information On This Product,
Address—address bus from the processor core. These bits are decoded in the
MPC180 to produce the individual module select lines to the execution units. Note
that the processor address bus might be 32 bits wide, while the MPC180 address
bus is only 12 bits wide.
msb = bit 0
lsb = bit 31
Data—bidirectional data bus. This bus is connected directly to the processor core.
msb = bit 0
lsb = bit 31
Chip Select. Active low signal that indicates when a data transfer is intended for
the MPC180.
Read/Write. Read/write line
1 read cycle
0 write cycle
Burst Transaction. Active low signal used in the 8260 interface that indicates when
the current read/write is a burst transfer.
Transfer Start. Transfer start pin for control port. This signal is asserted by the
850/860 to indicate the start of a bus cycle that transfers data to or from the
MPC180. This is used by the MPC180 along with CS, R/W, and A to begin a
transfer.
