 ### UART
 
-The UART module provides a general interface for serial communication which is decoupled from the actual backend driver. The backend driver might be UART0 (or UART1 if available), or it might be a software UART driver on chips (pins) that don't have hardware UART support.
+The UART module provides a general interface for serial communication which is decoupled from the actual backend driver. The backend driver might be UART0 (or UART1 if available), or it might be a user provided software UART driver on chips (pins) that don't have hardware UART support.
 
 The backend might also be interrupt driven and use some configurable receive/transmit buffer, or be blocking and not need any buffers. The buffers should only be allocated in interrupt driven mode and also be compile-time allocated.

 The I2C module is basically identical to SPI, just with a different protocol.
 
-### Timers
-
-The timers module allows the configuration of the hardware timers. Compile-time checks make sure that the requested time is actually achievable with the underlying hardware timer. The prescaler will be automatically calculated at compile-time based on the clock frequency, the hardware timer used and the time requested. The prescaler can also be specified directly.

-#### PWM
-
-The PWM mode of the hardware timer can also be used. Additionally, if PWM is needed on a pin that does not have hardware PWM support, a hardware timer can be used to implement software PWM.
