Description
TOC Register Write Protection*
This bit selects the enable/disable of write access to the
TOCS, OLSN, and OLSP bits in TOCR1.
0: Write access to the TOCS, OLSN, and OLSP bits is

TOC Select
This bit selects either the TOCR1 or TOCR2 setting to
be used for the output level in complementary PWM
mode and reset-synchronized PWM mode.
0: TOCR1 setting is selected
1: TOCR2 setting is selected
This bit selects the reverse phase output level in reset-
synchronized PWM mode/complementary PWM mode.
See table 9.30.
This bit selects the positive phase output level in reset-
synchronized PWM mode/complementary PWM mode.
See table 9.31.
