Timing definitions
Period during which the transponder waits for the start of response transmission after an EOF signal transmitted
from the reader/writer : t1_a
After detection of an EOF signal sent from the reader/writer, each transponder must wait for a certain time (t1_a)
before sending a response to the reader/writer. t1_a begins at the rising edge of the EOF pulse. The following
table lists the defined minimum, nominal, and maximum values of t1_a.
Also, ISO/IEC 15693-3 specifies that if the transponder detects a modulated signal from the reader/writer within
t1_a, the transponder must reset the t1_a timer and wait for another t1_a period before sending a response to
the reader/writer; otherwise, the slot counter must be incremented. On the MB89R118, however, the transponder
ignores all modulated signals sent from the reader/writer during the following tmit.
