Description
3
OLS1
0
R/W
Output Level Select 1
Selects the counter-phase output levels in reset
synchronous PWM mode or complementary PWM mode.
0: Initial output is high and the active level is low.
1: Initial output is low and the active level is high.
Output Level Select 0
2
OLS0
0
R/W
Selects the normal-phase output levels in reset
synchronous PWM mode or complementary PWM mode.
0: Initial output is high and the active level is low.
1: Initial output is low and the active level is high.
Figure 13.4 shows an example of outputs in reset
synchronous PWM mode and complementary PWM
mode when OLS1 = 0 and OLS0 = 0.

Combination Mode 1 and 0
00: Channel 0 and channel 1 operate normally
01: Channel 0 and channel 1 are used together to
operate in reset synchronous PWM mode
10: Channel 0 and channel 1 are used together to
operate in complementary PWM mode (transferred at
the trough)
11: Channel 0 and channel 1 are used together to
operate in complementary PWM mode (transferred at
the crest)
Note: When reset synchronous PWM mode or
complementary PWM mode is selected by these
bits, this setting has the priority to the settings for
PWM mode by each bit in TPMR. Stop TCNT_0
and TCNT_1 before making settings for reset
synchronous PWM mode or complementary PWM
mode.
