NOTES:
1. When programmng the IDT72T1895 with an input bus width of x9 and output bus width of x18, 4 write cycles will be required. When Reading the IDT72T1895 with an output
bus width of x9 and input bus width of x18, 4 read cycles will be required. A total of 6 program/read cycles will be required if both the input and output bus widths are set to x9.
2. Consecutive reads of the offset registers is not permtted. The read operation must be disabled for a mnimumof one RCLK cycle in between offset register accesses. (Please
refer to Figure 22,
Parallel Read of Programmable Flag Registers (IDT Standard and FWFT Modes)
for more details).
