Data
Notes : • PA is address of the memory location to be programmed.
• PD is data to be programmed at byte address.
• DQ7 is the output of the complement of the data written to the device.
• DOUT is the output of the data written to the device.
• Figure indicates the last two bus cycles out of four bus cycle sequence.
• These waveforms are for the × 16 mode. These address differ from × 8 mode.
