TinyPowerTM A/D Flash Type 8-Bit MCU with LCD & EEPRO

PWM Mode/ Single Pulse Output 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/

Single Pulse Output Mode. It has no effect if the TM is in the Timer/Counter Mode. In

the Compare Match Output Mode it determines the logic level of the TM output pin

before a compare match occurs. In the PWM Mode it determines if the PWM signal is

active high or active low.

Bit 2

T2POL: TP2_0, TP2_1 Output polarity Control

0: Non-invert

1: Invert

This bit controls the polarity of the TP2_0 or TP2_1 output pin. When the bit is set

high the TM output pin will be inverted and not inverted when the bit is zero. It has no

effect if the TM is in the Timer/Counter Mode.

Bit 1

T2DPX: TM2 PWM period/duty Control

0: CCRP - period; CCRA - duty

1: CCRP - duty; CCRA - period

This bit, determines which of the CCRA and CCRP registers are used for period and

duty control of the PWM waveform.

Bit 0

T2CCLR: Select TM2 Counter clear condition

0: TM2 Comparator P match

1: TM2 Comparator A match

This bit is used to select the method which clears the counter. Remember that the

Standard TM contains two comparators, Comparator A and Comparator P, either of

which can be selected to clear the internal counter. With the T2CCLR bit set high, the

counter will be cleared when a compare match occurs from the Comparator A. When

the bit is low, the counter will be cleared when a compare match occurs from the

Comparator P or with a counter overflow. A counter overflow clearing method can

only be implemented if the CCRP bits are all cleared to zero. The T1CCLR bit is not

used in the PWM, Single Pulse or Input Capture Mode.
