IDT72T3695, 65,536 for the IDT72T36105, 131,072 for the IDT72T36115 and 262,144 for the IDT72T36125.
In FWFT Mode: D=1,025 for the IDT72T3645, 2,049 for the IDT72T3655, 4,097 for the IDT72T3665, 8,193 for the IDT72T3675, 16,385 for the IDT72T3685, 32,769 for the IDT72T3695,
65,537 for the IDT72T36105, 131,073 for the IDT72T36115 and 262,145 for the IDT72T36125.
3.
PAF is asserted to LOW on WCLK transition and reset to HIGH on RCLK transition.
4. Select this mode by setting PFM LOW during Master Reset.
5.
RCS = LOW.
