DUAL 12-BIT AUTORELOAD TIMER 4 (Cont’d)
8. Set the OP_EN bit in the PWM3CSR register to
enable one-pulse mode.
9. Enable the PWM3 output by setting the OE3 bit
in the PWMCR register.
The "Wait for Overflow event" in step 6 can be re-
placed by forced update (writing the FORCE2 bit).

Note 1: When OP_EN=0, LTIC edges are not taken into account as the timer runs in PWM mode.

Follow the same procedure for PWM2 with the bits
corresponding to PWM2.
Note: When break is applied in one-pulse mode,
the CNTR2, DCR2/3 & ATR2 registers are reset.
Consequently, these registers have to be initial-
ized again when break is removed.
