Offset:
• SWRST: Software Reset
0: No effect.
1: Generates a software reset.
A software triggered hardware reset of the channel is performed. It resets all the registers, including PIO and PMC registers
(except GPTX_PMSR).
• CLKEN: Counter Clock Enable
0: No effect.
1: Enables counter clock if CLKDIS = 0.
• CLKDIS: Counter Clock Disable
0: No effect.
1: Disables counter clock.
• SWTRG: Software Trigger
0: No effect.
1: Generates a software trigger.
This bit generates a software trigger for resetting and starting the counter at the next valid counter clock edge when the
counter clock is enabled.
