Programming Considerations

Within the user program, one of the things first to consider is port initialisation. After a reset, all 
of the I/O data and port control registers will be set to high. This means that all I/O pins will be 
defaulted to an input state, the level of which depends on the other connected circuitry and whether 
pull-high selections have been chosen. If the port control registers are then programmed to setup 
some pins as outputs, these output pins will have an initial high output value unless the associated 
port data registers are first programmed. Selecting which pins are inputs and which are outputs can 
be achieved byte-wide by loading the correct values into the appropriate port control register or 
by programming individual bits in the port control register using the “SET [m].i” and “CLR [m].i” 
instructions. Note that when using these bit control instructions, a read-modify-write operation takes 
place. The microcontroller must first read in the data on the entire port, modify it to the required new 
bit values and then rewrite this data back to the output ports. 
Port A has the additional capability of providing wake-up functions. When the device is in the 
SLEEP or IDLE Mode, various methods are available to wake the device up. One of these is a high 
to low transition of any of the Port A pins. Single or multiple pins on Port A can be setup to have this 
function.

Timer Modules – TM

One of the most fundamental functions in any microcontroller devices is the ability to control and 
measure time. To implement time related functions the device includes several Timer Modules, 
generally 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 two 
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 Periodic TM sections.

Introduction

These devices contain four TMs and each individual TM can be categorised as a certain type, 
namely Compact Type TM, Standard Type TM or Periodic Type TM. Although similar in nature, 
the different TM types vary in their feature complexity. The common features to all of the Compact, 
Standard and Periodic 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.
