| * This file provides firmware functions to manage the following | |
| * functionalities of the Timer Extended peripheral: | |
| * + Time Master and Slave synchronization configuration | |
| * + Time OCRef clear configuration | |
| * + Timer remapping capabilities configuration | |

| ============================================================================== | |
| ##### TIMER Extended features ##### | |
| ============================================================================== | |
| [..] | |
| The Timer Extended features include: | |
| (#) Synchronization circuit to control the timer with external signals and to | |
| interconnect several timers together. | |
