Timer Output Level Buffer Register (TOLBR)

TOLBR is an 8-bit readable/writable register that functions as a buffer for TOCR2 and specifies the PWM output level in
complementary PWM mode and reset-synchronized PWM mode.

These bits are always read as 0. The write value should always be 0.
0 R/W Specifies the buffer value to be transferred to the OLS3N bit in TOCR2.
0 R/W Specifies the buffer value to be transferred to the OLS3P bit in TOCR2.
0 R/W Specifies the buffer value to be transferred to the OLS2N bit in TOCR2.
0 R/W Specifies the buffer value to be transferred to the OLS2P bit in TOCR2.
0 R/W Specifies the buffer value to be transferred to the OLS1N bit in TOCR2.
0 R/W Specifies the buffer value to be transferred to the OLS1P bit in TOCR2.
[1] [1] Set bit TOCS in TOCR1 to 1 to enable the TOCR2 setting.
[2] Use bits BF1 and BF0 in TOCR2 to select the TOLBR buffer
transfer timing. Use bits OLS3N to OLS1N and OLS3P to OLS1P
to specify the PWM output levels.
[2]
[3] The TOLBR initial setting must be the same value as specified in
bits OLS3N to OLS1N and OLS3P to OLS1P in TOCR2.
