Serial Data Output:
This pin will serially output the contents of the specified Command Register, dur-
ing “Read” Operations. The data, on this pin, will be updated on the falling edge of
the SCLK input signal. This pin will be tri-stated upon completion of data transfer.

Received Clock Edge Select Input:
Hardware Mode
1. When RCLKES = “0”, then RPOS and RNEG are updated on the falling edge
of RCLK
2. When RCLKES = “1”, then RPOS and RNEG are updated on the rising edge
of RCLK
NOTE: This applies to all channels.
Host Mode
Connect this pin to GND when the 71D04 is configured in the Host Mode.
Internal 50 K Ohm pull-down resistor.
