for controlling power off function. The GPIO20 can be used for device low power mode; it will remove power from the peripherals
in suspend mode. Once USB power is restored, the power to the peripherals may be enabled. The SL11R BIOS will execute the
pull up interrupt upon power-up. To use this feature, the GPIO29 pin must be connected to the DATA+ line of the USB connector
(see Figure below). For more information about this function, see the [Ref. 1] SL11R_BIOS.

The SL11R Controller supports four Programmable Digital Pulse output channels. These channels can also be used for Pulse
Width Modulation (PWM) operation. Operation is directed by the PWM Control Register, Maximum Count Register, and the
individual Start and Stop Counter Registers. These are provided for each of the four output channels. To set up PWM operation,
the Maximum Count Register is set to the desired maximum count value. Then the start and stop value for each channel is written
with the required values. The start and stop values are chosen to achieve the desired pulse widths during each cycle. When the
channels are disabled (by the Control Register), the associated I/O pins revert to GPIO use.
Note: The RCLK is the resulting clock (see the Speed Control Register (0xC006: R/W)).
