##### How to use this driver #####
|
===============================================================================
|
[..] This driver provides functions for:
|
(#) Remapping the memory accessible in the code area using
|
SYSCFG_MemoryRemapConfig().
|
(#) Manage the EXTI lines connection to the GPIOs using
|
SYSCFG_EXTILineConfig().
|
(#) Routing of I/Os toward the input captures of timers (TIM2, TIM3 and TIM4).
|
(#) Input routing of COMP1 and COMP2.
|
(#) Routing of internal reference voltage VREFINT to PB0 and PB1.
|
(#) The RI registers can be accessed only when the comparator
|
APB interface clock is enabled.
|
To enable comparator clock use:
|
RCC_APB1PeriphClockCmd(RCC_APB1Periph_COMP, ENABLE).
|
Following functions uses RI registers:
|
(++) SYSCFG_RIDeInit()
|
(++) SYSCFG_RITIMSelect()
|
(++) SYSCFG_RITIMInputCaptureConfig()
|
(++) SYSCFG_RIResistorConfig()
|
(++) SYSCFG_RIChannelSpeedConfig()
|
(++) SYSCFG_RIIOSwitchConfig()
|
(++) SYSCFG_RISwitchControlModeCmd()
|
(++) SYSCFG_RIHysteresisConfig()
|
(#) The SYSCFG registers can be accessed only when the SYSCFG
|
interface APB clock is enabled.
|
To enable SYSCFG APB clock use:
|
RCC_APB2PeriphClockCmd(RCC_APB2Periph_SYSCFG, ENABLE);
|
Following functions uses SYSCFG registers:
|
(++) SYSCFG_DeInit()
|
(++) SYSCFG_MemoryRemapConfig()
|
(++) SYSCFG_GetBootMode()
|
(++) SYSCFG_USBPuCmd()
|
(++) SYSCFG_EXTILineConfig()
