The pin's function of RM48 MCU

dison wang

Hello ,

I have a question about the pin's function of RM48 MCU.

I know the GIOA and GIOB were called GIO in document. and
GIOA support external interrupt capability.

Most of rest pin can work as a GIO. Do they support
external interrupt capability? or which pin also support external interrupt
capability like GIOA in rest of pins.

What is difference between the GIOA/B and rest of pins
which work as GIO?

Connected to stick, Are there just 10 pins of GIOA
(0,1,2,5,6,7)and GIOB(0,1,2,3) in the RM48l950PGE ?

Thanks!

Hello,

Only the dedicated GIO pins can support external interrupt capability. External interrupt capable GIO pins should be noted in the product datasheet.

The dedicated GIO pins are implemented in the GIO peripheral module instead of implemented inside each peripheral function.

Sorry, but I have no details of the USB stick design.

Karl

Dison,

You can download the schematics of the RM48 USB sick here.

On TMS570RMx all GIOA and GIOB have interrupt capability.
