From the datasheet: "The TMU initiates a read cycle by setting the strobe signal, not(Rstrobe), to a low state, indicating that the data transfer is about to begin. The serial Rdata sequence starts with a TAG bit, followed by the 40-bit data (R0 to R39). R39 (MSB) is the sign bit. Following the last data bit (R39), the strobe signal (Rstrobe) goes high for two clock cycles, indicating the end of the transaction."
The first mention of Rstrobe is not(Rstrobe) going low to indicate data transfer. The second mention, in the fourth sentence is (normal) Rstrobe going high for two clock cycles. Not(Rstrobe) going low and Rstrobe going high sound like the same thing to me. I'm reading data to an FPGA. How can I accurately sample data? What combination of rising and falling edges of Rstrobe and not(Rstrobe) am I looking for? The datasheet seems ambiguous to me here... Thank you!
