Data Timing
The system microcontroller should assert an active
low data request pulse for minimum duration of
200ns; this is specified by the SQ
PULSE
. Upon sens-
ing the rising edge of the end of the data request
pulse, the AAT3686 status data control will reply the
data word back to the system microcontroller after a
delay defined by the data report time specification
T
DATA(RPT)
. The period of the following group of data
pulses will be defined by the T
DATA
specification.
