|
45 | e80cfcfc | bellard | * The serial ports implement full AMD AM8530 or Zilog Z8530 chips,
|
46 | e80cfcfc | bellard | * mouse and keyboard ports don't implement all functions and they are
|
47 | e80cfcfc | bellard | * only asynchronous. There is no DMA.
|
48 | e80cfcfc | bellard | *
|
49 | b4ed08e0 | blueswir1 | * Z85C30 is also used on PowerMacs. There are some small differences
|
50 | b4ed08e0 | blueswir1 | * between Sparc version (sunzilog) and PowerMac (pmac):
|
51 | b4ed08e0 | blueswir1 | * Offset between control and data registers
|
52 | b4ed08e0 | blueswir1 | * There is some kind of lockup bug, but we can ignore it
|
53 | b4ed08e0 | blueswir1 | * CTS is inverted
|
54 | b4ed08e0 | blueswir1 | * DMA on pmac using DBDMA chip
|
55 | b4ed08e0 | blueswir1 | * pmac can do IRDA and faster rates, sunzilog can only do 38400
|
56 | b4ed08e0 | blueswir1 | * pmac baud rate generator clock is 3.6864 MHz, sunzilog 4.9152 MHz
