RDBYPASS

 

Reference divider bypass control. When this bit is set to 1 the PLL reference divider is bypassed

 

 

 

(i.e., FPLLIN = FCLKREF). When this bit is set to 0, the reference clock to the PLL is divided by the

 

 

 

reference divider (i.e., FPLLIN = FCLKIN / (RDRATIO+4)). The RDRATIO bits specify the divider value.

 

 

0

Use the reference divider.

 

 

1

Bypass the reference divider.

Divider ratio bits for the reference divider. Divider value = RDRATIO + 4. For example, setting

 

 

 

RDRATIO = 0 means divide the input clock rate by 4.
