 Introduction
 ------------
 
-The {IDF_TARGET_NAME} chip contains two hardware timer groups. Each group has two general-purpose hardware timers. They are all {SOC_TIMER_GROUP_COUNTER_BIT_WIDTH}-bit generic timers based on 16-bit pre-scalers and {SOC_TIMER_GROUP_COUNTER_BIT_WIDTH}-bit up / down counters which are capable of being auto-reloaded.
