(1) Interrupt events GPINT4, GPINT5, GPINT6, and GPINT7 are outputs from the GPIO module (GP).
They originate from the device pins GP[4](EXT_INT4)/AMUTEIN1, GP[5](EXT_INT5)/AMUTEIN0,
GP[6](EXT_INT6), and GP[7](EXT_INT7). These pins can be used as edge-sensitive EXT_INTx with
polarity controlled by the External Interrupt Polarity Register (EXTPOL.[3:0]). The corresponding pins
must first be enabled in the GPIO module by setting the corresponding enable bits in the GP Enable
Register (GPEN.[7:4]), and configuring them as inputs in the GP Direction Register (GPDIR.[7:4]).
These interrupts can be controlled through the GPIO module in addition to the simple EXTPOL.[3:0]
bits. For more information on interrupt control via the GPIO module, see the TMS320C6000™ DSP
General-Purpose Input/Output (GPIO) Reference Guide (literature number SPRU584).
7.4 External Interrupt Sources
The C6713/13B device supports many external interrupt sources as indicated in Table 7-5. Control of the
interrupt source is done by the associated module and is made available by enabling the corresponding
binary interrupt selector value (see Table 7-4 shaded rows). Because of pin multiplexing and module
usage, not all external interrupt sources are available at the same time.
