Each Counter/timer is designed to count cycles of the peripheral clock (PCLK) or an
externally supplied clock and can optionally generate interrupts or perform other actions at
specified timer values based on four match registers. Each counter/timer also includes
one capture input to trap the timer value when an input signal transitions, optionally
generating an interrupt.
In PWM mode, three match registers on CT16B0 and two match registers on CT16B1 can
be used to provide a single-edge controlled PWM output on the match output pins. It is
recommended to use the match registers that are not pinned out to control the PWM cycle
length.
Remark: The 16-bit counter/timer0 (CT16B0) and the 16-bit counter/timer1 (CT16B1) are
functionally identical except for the peripheral base address.

The peripheral clocks (PCLK) to the 16-bit timers are provided by the system clock (see

3). These clocks can be disabled through bit 7 and 8 in the SYSAHBCLKCTRL
(Table
gives a brief summary of each of the counter/timer related pins.
Description
Capture Signal:
A transition on a capture pin can be configured to load the Capture Register with the
value in the counter/timer and optionally generate an interrupt.
Counter/Timer block can select a capture signal as a clock source instead of the PCLK
derived clock. For more details see
External Match Outputs of CT16B0/1:
When a match register of CT16B0/1 (MR3:0) equals the timer counter (TC), this output
can either toggle, go LOW, go HIGH, or do nothing. The External Match Register
(EMR) and the PWM Control Register (PWMCON) control the functionality of this
output.
