RX23W Group 23. Multi-Function Timer Pulse Unit 2 (MTU2a)
23.2.19 Timer Output Level Buffer Registers (TOLBR)
The TOLBR registers function as buffer registers for the TOCR2 register and specify the PWM output level in
complementary PWM mode and reset-synchronized PWM mode.
Figure 23.3 shows an example of the PWM output level setting procedure in buffer operation.

Bit Symbol Bit Name Description R/W
b0 OLS1P Output Level Select 1P Specify the buffer value to be transferred to the OLS1P bit in TOCR2. R/W
b1 OLS1N Output Level Select 1N Specify the buffer value to be transferred to the OLS1N bit in TOCR2. R/W
b2 OLS2P Output Level Select 2P Specify the buffer value to be transferred to the OLS2P bit in TOCR2. R/W
b3 OLS2N Output Level Select 2N Specify the buffer value to be transferred to the OLS2N bit in TOCR2. R/W
b4 OLS3P Output Level Select 3P Specify the buffer value to be transferred to the OLS3P bit in TOCR2. R/W
b5 OLS3N Output Level Select 3N Specify the buffer value to be transferred to the OLS3N bit in TOCR2. R/W
b7, b6 — Reserved These bits are read as 0. The write value should be 0. R/W
[1] Set the TOCR1.TOCS bit to 1 to enable the TOCR2 register setting.
[2] Use the TOCR2.BF[1:0] bits to select the TOLBR buffer transfer timing.
Use bits OLS3N to OLS1N and OLS3P to OLS1P to specify the PWM
output levels.
[3] The TOLBR register initial setting must be the same value as specified
in bits OLS3N to OLS1N and OLS3P to OLS1P in the TOCR2 register.
