Notes:
1. The signal names used in Figure 48 and Figure 49 are the PC/AT Compatible and Bidirectional mode signal names.
2. During EPP mode and Bidirectional mode, PPDWE acts as the parallel port chip select and is asserted for both reads and
3. These timings are only valid for EPP mode.
4. BUSY is asserted to add wait states to the parallel port access.
5. DBUFOE and DBUFRDL may be required when using the VESA local bus interface or a x32 DRAM interface.
writes. For PC/AT Compatible mode, PPDWE will be asserted only for parallel port write cycles.
