Description
Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.
SCL Clock Period
This field specifies the period of the SCL clock.
SCL_PRD = 2*(1 + TPR)*(SCL_LP + SCL_HP)*CLK_PRD
where:
SCL_PRD is the SCL line period (I
TPR is the Timer Period register value (range of 1 to 255).
SCL_LP is the SCL Low period (fixed at 6).
SCL_HP is the SCL High period (fixed at 4).
