t HD;STA
SCL clock frequency
bus free time between a
STOP and START
condition
hold time (repeated)
START condition; after this
period, the first clock pulse
is generated
SCL LOW period
SCL HIGH period
set-up time for a repeated
START condition
DATA hold time
DATA set-up time
rise time of both SDA and
SCL signals
fall time of both SDA and
SCL signals
set-up time for STOP
condition
capacitive load for each
bus line
pulse width of spikes to be
suppressed by input filter
