General Purpose Timer Units (GPT12)
Port Control
Port pins to be used for timer input signals must be switched to input (bitfield PC in the respective port control
register must be 0xxx
B
) and must be selected via register PISEL.
Port pins to be used for timer output signals must be switched to output and the alternate timer output signal
must be selected (bitfield PC in the respective port control register must be 1xxx
B
).
Note:
For a description of the port control registers, please refer to chapter “Parallel Ports”.
Interrupts
The GPT12 has six interrupt request lines.
Interrupt nodes to be used for timer interrupt requests must be enabled and programmed to a specific
interrupt level.
Debug Details
While the module GPT is disabled, its registers can still be read. While disabled the following registers can be
written: PISEL, T5CON.
