/* PWM
*
* The STM3240G-Eval has no real on-board PWM devices, but the board can be
* configured to output a pulse train using TIM4 CH2. This pin is used by FSMC is
* but is also connected to the Motor Control Connector (CN5) just for this
* purpose:
* configured to output a pulse train using the following:
*
* PD13 FSMC_A18 / MC_TIM4_CH2OUT pin 33 (EnB)
*
* FSMC must be disabled in this case! PD13 is available at:
*
* Daughterboard Extension Connector, CN3, pin 32 - available
* TFT LCD Connector, CN19, pin 17 -- not available without removing the LCD.
* If FSMC is not used:
* TIM4 CH2OUT: PD13 FSMC_A18 / MC_TIM4_CH2OUT
* Daughterboard Extension Connector, CN3, pin 32
* Motor Control Connector CN15, pin 33 -- not available unless you bridge SB14.
*
* TIM1 CH1OUT: PE9 FSMC_D6
* Daughterboard Extension Connector, CN2, pin 24
*
* TIM1_CH2OUT: PE11 FSMC_D8
* Daughterboard Extension Connector, CN2, pin 26
*
* TIM1_CH3OUT: PE13 FSMC_D10
* Daughterboard Extension Connector, CN2, pin 28
*
* TIM1_CH4OUT: PE14 FSMC_D11
* Daughterboard Extension Connector, CN2, pin 29
*
* If OTG FS is not used
*
* TIM1_CH3OUT: PA10 OTG_FS_ID
* Daughterboard Extension Connector, CN3, pin 14
*
* TIM1_CH4OUT: PA11 OTG_FS_DM
* Daughterboard Extension Connector, CN3, pin 11
*
* If DMCI is not used
*
* TIM8 CH1OUT: PI5 DCMI_VSYNC & MC
* Daughterboard Extension Connector, CN4, pin 4
*
* TIM8_CH2OUT: PI6 DCMI_D6 & MC
* Daughterboard Extension Connector, CN4, pin 3
*
* TIM8_CH3OUT: PI7 DCMI_D7 & MC
* Daughterboard Extension Connector, CN4, pin 2
*
* If SDIO is not used
*
* TIM8_CH3OUT: PC8 MicroSDCard_D0 & MC
* Daughterboard Extension Connector, CN3, pin 18
*
* TIM8_CH4OUT: PC9 MicroSDCard_D1 & I2S_CKIN (JP16)
* Daughterboard Extension Connector, CN3, pin 15
*
* Others
*
* TIM8 CH1OUT: PC6 I2S_MCK & Smartcard_IO (JP21 open)
