Bit 7~6

TnM1~TnM0: Select TMn Operating Mode

00: Compare Match Output Mode

01: Undefined

10: PWM Mode

11: Timer/Counter Mode

These bits setup the required operating mode for the TM. To ensure reliable operation

the TM should be switched off before any changes are made to the TnM1 and TnM0

bits. In the Timer/Counter Mode, the TM output pin control must be disabled.

Bit 5~4

TnIO1~TnIO0: Select TPn_0, TPn_1 output function

Compare Match Output Mode

00: No change

01: Output low

10: Output high

11: Toggle output

PWM Mode

00: PWM Output inactive state

01: PWM Output active state

10: PWM output

11: Undefined

These two bits are used to determine how the TM output pin changes state when a

certain condition is reached. The function that these bits select depends upon in which

mode the TM is running.

In the Compare Match Output Mode, the TnIO1 and TnIO0 bits determine how the

TM output pin changes state when a compare match occurs from the Comparator A.

The TM output pin can be setup to switch high, switch low or to toggle its present

state when a compare match occurs from the Comparator A. When the bits are both

zero, then no change will take place on the output. The initial value of the TM output

pin should be setup using the TnOC bit in the TMnC1 register. Note that the output

level requested by the TnIO1 and TnIO0 bits must be different from the initial value

setup using the TnOC bit otherwise no change will occur on the TM output pin when a

compare match occurs. After the TM output pin changes state it can be reset to its

initial level by changing the level of the TnON bit from low to high.

In the PWM Mode, the TnIO1 and TnIO0 bits determine how the TM output pin

changes state when a certain compare match condition occurs. The PWM output

function is modified by changing these two bits. It is necessary to only change the

values of the TnIO1 and TnIO0 bits only after the TMn has been switched off.

Unpredictable PWM outputs will occur if the TnIO1 and TnIO0 bits are changed when

the TM is running.

Bit 3

TnOC: TPn_0, TPn_1 Output control bit

Compare Match Output Mode

0: Initial low

1: Initial high

PWM Mode

0: Active low

1: Active high

This is the output control bit for the TM output pin. Its operation depends upon

whether TM is being used in the Compare Match Output Mode or in the PWM Mode.
