DIVCORE_CLK

1. Watchdog clock sources are selected by WDOGx_CS[CLK]

2. ERCLK is either from an external pin or from the SCG Internal OSC (SOSC) and configured with the

SCG_SOSCCFG[EREFS] bit.

3. LPTMR clock sources are selected by LPTMR_PSR[PCS]

4. RTC clock sources are selected by RTC_CR[LPOS]

5. For the USB FS OTG controller to operate, the minimum required DIVCORE_CLK is 24 MHz (half of USB functional

clock)

6. An additional external clock USB_CLKIN, can also selected via PCCUSB0FS, and device's PORTx MUX field

7. Additional 3bit Divide field and 1-bit Fractional field reside in PCCUSB0FS register
