Introduction
One of the most fundamental functions in any microcontroller device is the ability to control and
measure time. To implement time related functions each device includes several Timer Modules,
abbreviated to the name TM. The TMs are multi-purpose timing units and serve to provide operations
such as Timer/Counter, Input Capture, Compare Match Output and Single Pulse Output as well as
being the functional unit for the generation of PWM signals. Each of the TMs has either two or three
individual interrupts. The addition of input and output pins for each TM ensures that users are provided
with timing units with a wide and flexible range of features.
The common features of the different TM types are described here with more detailed information
provided in the individual Compact, Standard and Enhanced TM sections.
The devices contain up to two TMs with each TM having a reference name of TM0 and TM1. Each
individual TM can be categorised as a certain type, namely Compact Type TM (CTM), Standard Type
TM (STM) or Enhanced Type TM (ETM). Although similar in nature, the different TM types vary in
their feature complexity. The common features to all of the Compact, Standard and Enhanced TMs
will be described in this section and the detailed operation regarding each of the TM types will be
described in separate sections. The main features and differences between the three types of TMs are
summarised in the accompanying table.
Each device in the series contains a specific number of either Compact Type, Standard Type and En-
hanced Type TM units which are shown in the table together with their individual reference name,
TM0~TM1.
