12-bit auto-reload timer (AT)
Introduction
The 12-bit auto-reload timer can be used for general-purpose timing functions. It is based on
a free-running 12-bit upcounter with a PWM output channel.

Functional description
PWM mode
This mode allows a pulse width modulated signals to be generated on the PWM0 output pin
with minimum core processing overhead. The PWM0 output signal can be enabled or
disabled using the OE0 bit in the PWMCR register. When this bit is set the PWM I/O pin is
configured as output push-pull alternate function.
CMPF0 is available in PWM mode (see
(PWM0CSR)).
