TMS320F28377D: External interrupt GPIO

David D
Intellectual 580 points
Part Number: TMS320F28377D
Other Parts Discussed in Thread: SYSCONFIG

Hello,

TMS320F28377D's technical reference manual (5.3.3) mentions "...five external interrupt signals which can be connected to most of the general-purpose input/output (GPIO) pins on the device."

This means that there are some GPIOs that are NOT capable of handling interrupts.

Which GPIOs are these? Where it is documented? Is there some cloud tool (eg. SysConfig) that allows to determine this ?

Regards,

David.

    David,

    In F28377D, any GPIO can be configured to trigger external interrupts using INPUT XBAR. This information is captured in Pg1188 in TRM.

     XINT5 - INPUT14 (Can be configured to be triggered by any GPIO using INPUTXBAR)
     XINT4 - INPUT13 (Can be configured to be triggered by any GPIO using INPUTXBAR)
     XINT3 - INPUT6  (Can be configured to be triggered by any GPIO using INPUTXBAR)
     XINT2 - INPUT5  (Can be configured to be triggered by any GPIO using INPUTXBAR)
     XINT1 - INPUT4  (Can be configured to be triggered by any GPIO using INPUTXBAR)

    Regards,

    Manoj
