22.2.1 Features
The eMIOS timer module provides the capability to generate or measure events in hardware.
The eMIOS module features include:
• Twenty-four 24-bit wide channels
• 3 channels’ internal timebases can be shared between channels
• 1 timebase from eTPU2 can be imported and used by the channels
• Global enable feature for all eMIOS and eTPU timebases
• Dedicated pin for each channel (not available on all package types)
Each channel (0–23) supports the following functions:
• General-purpose input/output (GPIO)
