Timer Period
This field is used in the equation to configure
SCL_PERIOD
:
SCL_PERIOD = 2×(1 + TPR)×(SCL_LP + SCL_HP)×CLK_PRD
where:
SCL_PRD
is the SCL line period (I
2
C clock).
TPR
is the Timer Period register value (range of 1 to 127).
SCL_LP
is the SCL Low period (fixed at 6).
SCL_HP
is the SCL High period (fixed at 4).
CLK_PRD
is the system clock period in ns.
