mbed_official 76:aeb1df146756 14 ##### How to use this driver #####
mbed_official 76:aeb1df146756 15 ===============================================================================
mbed_official 76:aeb1df146756 16 [..] This driver provides functions for:
mbed_official 76:aeb1df146756 17 (#) Remapping the memory accessible in the code area using
mbed_official 76:aeb1df146756 18 SYSCFG_MemoryRemapConfig().
mbed_official 76:aeb1df146756 19 (#) Manage the EXTI lines connection to the GPIOs using
mbed_official 76:aeb1df146756 20 SYSCFG_EXTILineConfig().
mbed_official 76:aeb1df146756 21 (#) Routing of I/Os toward the input captures of timers (TIM2, TIM3 and TIM4).
mbed_official 76:aeb1df146756 22 (#) Input routing of COMP1 and COMP2.
mbed_official 76:aeb1df146756 23 (#) Routing of internal reference voltage VREFINT to PB0 and PB1.
mbed_official 76:aeb1df146756 24 (#) The RI registers can be accessed only when the comparator
mbed_official 76:aeb1df146756 25 APB interface clock is enabled.
mbed_official 76:aeb1df146756 26 To enable comparator clock use:
mbed_official 76:aeb1df146756 27 RCC_APB1PeriphClockCmd(RCC_APB1Periph_COMP, ENABLE).
mbed_official 76:aeb1df146756 28 Following functions uses RI registers:
mbed_official 76:aeb1df146756 29 (++) SYSCFG_RIDeInit()
mbed_official 76:aeb1df146756 30 (++) SYSCFG_RITIMSelect()
mbed_official 76:aeb1df146756 31 (++) SYSCFG_RITIMInputCaptureConfig()
mbed_official 76:aeb1df146756 32 (++) SYSCFG_RIResistorConfig()
mbed_official 76:aeb1df146756 33 (++) SYSCFG_RIChannelSpeedConfig()
mbed_official 76:aeb1df146756 34 (++) SYSCFG_RIIOSwitchConfig()
mbed_official 76:aeb1df146756 35 (++) SYSCFG_RISwitchControlModeCmd()
mbed_official 76:aeb1df146756 36 (++) SYSCFG_RIHysteresisConfig()
mbed_official 76:aeb1df146756 37 (#) The SYSCFG registers can be accessed only when the SYSCFG
mbed_official 76:aeb1df146756 38 interface APB clock is enabled.
mbed_official 76:aeb1df146756 39 To enable SYSCFG APB clock use:
mbed_official 76:aeb1df146756 40 RCC_APB2PeriphClockCmd(RCC_APB2Periph_SYSCFG, ENABLE);
mbed_official 76:aeb1df146756 41 Following functions uses SYSCFG registers:
