Implementation of the GPT12 Module
This chapter describes the implementation of the GPT12 module in the TLE984x device.
16.6.1
Module Connections
Besides the described intra-module connections, the timer unit blocks GPT1 and GPT2 are connected to their
environment in two basic ways:
•
Internal connections
interface the timers with on-chip resources such as clock generation unit, interrupt
controller, or other timers.
The GPT module is clocked with the TLE984x system clock, so

.
•
External connections
interface the timers with external resources via port pins.
Figure 114 GPT Module Interfaces
Note:
The GPT12E output signal ‘T6OFL’ is connected to the CAPCOM2 input ‘TOUF’ and to the GSC..
The following table
(GPT12) shows the digital connections of the GPT12 module with other modules
or pins in the TLE984x device.
