Enhanced Motor Control Timer (eTimer)
• Programmable input filter
• Counting start can be synchronized across counters
20.3 External signal descriptions
The eTimer module has 6 external signals that can be used as either inputs or outputs. There are also 3
auxiliary inputs. The eTimer also interfaces to the Peripheral Bus.
20.3.1 TIO[5:0] - Timer Input/Outputs
These pins can be independently configured to be either timer input sources or output flags.
20.3.2 TAI[2:0] - Timer Auxiliary Inputs
These pins act as alternate input choices for the timer channels.
The module-to-module input signals are described in Table 20-1. Additional information on
module-to-module interaction is shown in Figure 13-2.
