TOCL
0
R/(W)*¹ TOC Register Write Protection*²
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
enabled
1: Write access to the TOCS, OLSN, and OLSP bits is
disabled
2
TOCS
0
R/W 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
1
OLSN
0
R/W Output Level Select N*³
This bit selects the reverse phase output level in reset-
synchronized PWM mode/complementary PWM mode.
See table 10.30.
0
OLSP
0
R/W Output Level Select P*³
This bit selects the positive phase output level in reset-
synchronized PWM mode/complementary PWM mode.
See table 10.31.
Notes: 1. Setting the TOCL bit to 1 prevents accidental modification when the CPU goes out of
control.
2. Clearing the TOCS0 bit to 0 makes this bit setting valid.
