Timer Output Level Buffer Register (TOLBRA)
j = A
TOLBRA is buffer register for TOCR2A and specify the PWM output level in complementary PWM mode and reset-
synchronized PWM mode.
shows an example of the PWM output level setting procedure in buffer operation.

[3]
[1] Set bit TOCS in TOCR1j (j = A) to 1 to enable the TOCR2j setting.
[2] Use bits TOCR2j.BF[1:0] to select the TOLBRj buffer transfer timing.
Use bits OLS3N to OLS1N and OLS3P to OLS1P to specify the PWM output
levels.
[3] The TOLBRj initial setting must be the same value as specified in bits OLS3N
to OLS1N and OLS3P to OLS1P in TOCR2j.
