TOLBRA is buffer register for TOCR2A and specify the PWM output level in complementary PWM mode and reset-
synchronized PWM mode.
Figure 19.3 shows an example of the PWM output level setting procedure in buffer operation.

Description
Specify the buffer value to be transferred to the OLS1P bit in TOCR2j.
Specify the buffer value to be transferred to the OLS1N bit in TOCR2j.
Specify the buffer value to be transferred to the OLS2P bit in TOCR2j.
Specify the buffer value to be transferred to the OLS2N bit in TOCR2j.
Specify the buffer value to be transferred to the OLS3P bit in TOCR2j.
Specify the buffer value to be transferred to the OLS3N bit in TOCR2j.
These bits are read as 0. The write value should be 0.
[1]
[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.
[2]
[3] The TOLBRj initial setting must be the same value as specified in bits OLS3N
to OLS1N and OLS3P to OLS1P in TOCR2j.
