Select Transmit Clock Frequency on Port CLK2
Port CLK2 is the de-jittered DCO-X clock at a frequency of
00 = 1.544 MHz
01 = 3.088MHz
10 = 6.176 MHz
11 = 12.352 MHz
Select System Clock Frequency on Port CLK1
Port CLK1 is the de-jittered DCO-R clock at a frequency of
SIC2.SSC2=0:
000 = 8 kHz
001 = 2.048 MHz
010 = 4.096 MHz
011 = 8.192 MHz
100 = 16.384 MHz
101 to 111 = Not defined
SIC2.SSC2=1:
000 = 8 kHz
001 = 1.544 MHz
010 = 3.088 MHz
011 = 6.176 MHz
100 = 12.352 MHz
101 to 111 = Not defined
Note: If DCO-X is not used, no clock is output on pin CLK2
Note: If DCO-R is not active, no clock is output on pin CLK1
