The PWMOFF input processing control registers are used to set the active edge or level entered for PWM output
disable control from an external pin. For details about the PWM output disable function, see Section 10.8.18,
“PWM Output Disable Function.”
To set the PWMOFF input processing control bits, follow the procedure described below.
1. Write data ‘1’ to the PWMOFFnS write control bit (PWMOFFnSP).
2. After 1 above, write data ‘0’ to the PWMOFFnS write control bit (PWMOFFnSP) and the set value to the
PWMOFF input processing control bits (PWMOFFnS).
Note: • If a write cycle to any other area occurs between 1 and 2, what has successively been set above
has no effect and the written value is not reflected. Therefore, disable interrupts and DMA transfers
before setting the PWMOFF control bits. Be aware that a pair of two consecutive writes comprise
a write operation.
