NOTE:
1. X = 14 for the IDT72T7285, X = 15 for the IDT72T7295, X = 16 for the IDT72T72105, X = 17 for the IDT72T72115.
NOTE:
1. This timing diagram illustrates programming with an input bus width of 72 bits.
NOTES:
1. OE = LOW; RCS = LOW.
2. The timing diagram illustrates reading of offset registers with an output bus width of 72 bits.
3. The offset registers cannot be read on consecutive RCLK cycles. The read must be disabled (REN = HIGH) for a minimum of one RCLK cycle in between register accesses.
