Bit 6: RSYSCLKn Select (RSYSCLKSEL)
Bit 5: TSYSCLKn Select (TSYSCLKSEL)
Bit 4: TCLKn Select (TCLKSEL)
Bits 3 to 0: Clock Out Frequency Select (CLKOSEL[3:0]. CLKO output pin will use MCLK (1.544MHz or
2.048MHz or scaled version) as its reference. The following table shows how to configure for each frequency. For
best jitter performance use a 2.048MHz oscillator for MCLK.

CLKOSEL[3:0]
0 = Use RSYSCLKn pins for each receive system clock (Channels 1-4).
1 = Use BPCLK1 as the master clock for all four receive system clocks (Channels 1-4).
0 = Use TSYSCLKn pins for each transmit system clock (Channels 1-4).
1 = Use BPCLK1 as the master clock for all four transmit system clocks (Channels 1-4).
0 = Use TCLKn pins for each of the transmit clock (Channels 1-4).
1 = Use REFCLKIO as the master clock for all four transmit clocks (Channels 1-4).
