PRODUCTION DATA
For GPIOx to decode PWM input signals, configure the GPIOx_FMT bit for PWM decoding. GPIOx uses the time base configured in the GPIOx_PWM_TB[1:0] bits for PWM decoding. The decoded input value is provided in the GPIx_DAT[1:0] bit field. The GPIOs decode PWM signals with four different levels as specified in the GPI_DAT[1:0] bit field description.
The GPIx_DAT[1:0] bits need up to two PWM cycles to indicate the correct logic level after the PWM period or duty cycle applied to GPIOx changed.
