7.1.4 PWMCLK
7.1.5 USBCLK
S1D13A04
X37A-A-001-06
There is a relationship between the frequency of MCLK and PCLK that must be
maintained.
PWMCLK is the internal clock used by the Pulse Width Modulator for output to the panel.
The source clock options for PWMCLK may be selected as in the following table.
For further information on controlling PWMCLK, see “PWM Clock Configuration
Register” on page 114..
CLKUSB is an internal clock derived from USBCLK and should be fixed at 48MHz.
USBCLK must be active to access the USB Registers.
