The reset control register enables to reset the device
Write ‘1’ to enable sleep mode. hardware resets this bit to ‘0’ after it successfully enters sleep
mode.
Write ‘1’ to initiate a warm reset. Register content remains, state machine reset.
Write ‘1’ to initiate a soft reset. All registers content and state machines reset.
Write ‘1’ to enter the hibernate mode. Hardware resets this bit to ‘0’ after it successfully enters
hibernate mode.

This register enables to switch off the clock supply
Write ‘1’ to disable the clock to PWM unit.
Write ‘1’ to disable the clock to GPIO unit. Note that GPIO clock is required for PWM operation.
Write ‘1’ to disable the clock to FIFO unit. This must be set to ‘0’ if touch interrupt is required.
Write ‘1’ to disable the clock to TOUCH unit.
