The GPIO Direction Register 1 controls the direction of GPIOs 1 through 6. When muxable pins are
not configured as a GPIO ports the respective bits are ignored.
Bit 5 - 0 - GPIOx_DIR - Controls the input / output state of GPIOs. The bit is not used if the pin is not
configured as a GPIO.
The GPIO Output Configuration Register controls the output pin type of each GPIO pin. These settings
apply to the pin if it is configured as a GPIO output or a PWM. These bits do not apply if the pin is
configured as a DAC output or one of the three dedicated OVERTx pins (which are always open drain).
Bit 6 - PWM1_OT - Determines the output type for the PWM1 pin.
Bit 5 - 0 - GPIOx_OT - Determines the output type for GPIOx.
The GPIO Input Register indicates the state of the corresponding GPIO pin regardless of the
functionality of the pin (GPIO, PWM, or TACH) or the direction of the GPIO (input, push-pull output,

GPIO / PWM Pin Output Configuration Register
GPIO Input Register
‘0’ (default) - The GPIO is configured as an input.
‘1’ - The GPIO is configured as an output.
‘0’ (default) - The PWM1 output is configured as an open drain output (if enabled as a PWM
output).
‘1’ - The PWM1 output is configured as a push-pull output (if enabled as an a PWM output).
‘0’ (default) - GPIOx is configured as an open drain output (if enabled as an output).
‘1’ - GPIOxis configured as a push-pull output (if enabled as an output).
