System clock frequency.
System clock period.
SCL clock period.
Time from start condition to SCL
goes ‘low’.
SCL ‘low’ time after start condition.
Data setup time before positive edge
on SCL.
Data hold time after negative edge
on SCL.
SCL ‘low’ time after last bit before
stop condition.
Time from SCL goes ‘high’ to stop
condition.
Time from stop condition to start
condition.
Time from change on SDA until SCL
is released when the module is a
Slave that forces SCL ‘low’.
Width of IRQ signal.
Time from positive edge on SCL to
IRQ signal.
