than once. A LOW on the RT input during a rising RCLK edge initiates a
retransmit operation by setting the read pointer to the first location of the memory
array. A zero-latency retransmit timing mode can be selected using the
Retransmit timing Mode pin (RM). During Master Reset, a LOW on RM will select
zero-latency retransmit. A HIGH on RM during Master Reset will select normal
latency.
retransmitted will be placed on the output register with respect to the same
RCLK edge that initiated the retransmit based on RT being LOW.
