NOTES
1 The 82091AA does not contain IDE registers However the 82091AA provides the address block assignments for access-
ing the IDE registers that are located in the IDE device
2 The standard PC AT compatible logical I O address assignments are supported For example COM1 (3F8 – 3FFh) and
COM2 (2F8–2FFh) are part of the serial port assignments and LPT1 (3BC – 3BFh) LPT2 (378 – 37Fh) and LPT3
(278 – 27Fh) are part of the parallel port assignments
