Figure 10.8.22 Circuit Configurations of the PWM Output Disable Function (2)
There are following three methods to disable PWM outputs.
(1) Using the signal entered from an external pin (TIN16/PWMOFF0, TIN17/PWMOFF1 or TIN33/PWMOFF2)
to disable PWM outputs
The input signal on the external pin (TIN16/PWMOFF0) may be used to disable outputs from the ports P160/
TO21–P165/TO26 that are provided for the PWM outputs of the TOU0_0–TOU0_5 timers. Similarly, the
input signal on the external pin (TIN17/PWMOFF1) may be used to disable outputs from the ports P180/
TO29–P185/TO34 that are provided for the PWM outputs of the TOU1_0–TOU1_5 timers. Also, the input
signal on the external pin (TIN33/PWMOFF2) may be used to disable outputs from the ports P210/TO37–
P215/TO42 that are provided for the PWM outputs of the TOU2_0–TOU2_5 timers.
To disable PWM outputs using the input signal on the external pin (TIN16/PWMOFF0, TIN17/PWMOFF1 or
TIN33/PWMOFF2), set up the PWMOFF Input Processing Control Register (PWMOFFnCR) as described
below.
[Setting up the PWMOFF Input Processing Control Register]
When using TIN16/PWMOFF0 to disable PWM outputs
1. Write data '1' to the PWMOFF0CR register PWMOFF0SP bit.
2. After 1 above, write data '0' to the PWMOFF0SP bit and then data '000,' '001,' '010,' '011,' '10X' or
'11X' to the PWMOFF0S bit in succession.
Note: • If a write cycle to any other area occurs between 1 and 2, the value written to the PWMOFF0S
