System configuration controller (SYSCFG)

11.1

Introduction

The system configuration controller offers remapping capabilities of TIM3 channels on

different I/O ports. To use an alternate function, the corresponding peripheral must be

enabled in the peripheral registers. Alternate function remapping does not affect the GPIO

capabilities of the I/O ports (see Section 10: General purpose I/O ports (GPIO) on page 75).

Refer to Section 11.2: SYSCFG register for remapping capabilities on TIM3 channels.
