Table 47. CKN: Clocks, NETREF Selections, 0x01
Clock register 0x01 is CKN, the CT_NETREF select register. This register selects features for generating and rout-
ing the CT_NETREF signal.

7—6 NR12EN enables the selection between NETREF1 and NETREF2.
NR12EN = 00,
The value of NRSEL[3:0] of CKN determines what is routed to the
L_SCs.
NR12EN = 01,
Enable NETREF2 for output, route NETREF1 input to the L_SCs.
NR12EN = 10,
Enable NETREF1 for output, route NETREF2 input to the L_SCs.
NR12EN = 11,
Enable both NETREF[1:2] for output, route output of NETREF
divide-by-N to LSCs.
5
NDB = 0,
TODJAT pin comes from NETREF selector, and FROMDJAT pin
goes to NETREF divider.
NDB = 1,
NETREF selector goes directly to NETREF divider.
4
NRI inverts the output of the NETREF selector.
NRI = 0,
Normal.
NRI = 1,
Invert.
3—0 The NRSEL is similar to CKSEL but with fewer choices:
NRSEL = 0000,
Internal oscillator divided by 8.
NRSEL = 0001,
Internal oscillator.
NRSEL = 0010,
Select NETREF1 as input.
NRSEL = 0011,
Select NETREF2 as input.
NRSEL = 0100—0111, (Reserved.)
NRSEL = 1000—1111, Local references 0—7.
