Part Number: AM2634-Q1

Hi, Expert

I am studying EB tresos for DIO setting

I have a question, follow below chart.

How to know real hardware pin define for GPIOAB_Ch0?

I already reference this thread, but I still feel very confuse.

https://e2e.ti.com/support/microcontrollers/arm-based-microcontrollers-group/arm-based-microcontrollers---internal/f/arm-based-microcontrollers---internal-forum/1161207/am2634-mcal-eb24-configuration?tisearch=e2e-sitesearch&keymatch=GPIOAB#

I think we need an 101 guide to explain it.

Many Thanks

Hi Gibbs,

There are 9 Ports each of 16 channels except GPIOI.

GPIOAB --> 32 channels (0 to 31) (Consist of bank A and B)

GPIOCD --> 32 channels (31 to 63)

GPIOEF --> 32 channels (64 to 95)

GPIOGH --> 32 channels (96 to 127)

GPIOI --> 10 channels (128 to 137)

e.g. hardware gpio pin for GPIOCD_Ch0 is 32.

So, basically hardware gpio pin for GPIOAB_Ch0 is 0.

Thanks & Regards,
Milind.

Hi, Milind.

Thanks your replies.

Let's me double check your explanation.

GPIOAB_Ch0 --> gpio0

GPIOAB_Ch1 --> gpio1

......

GPIOAB_Ch31 --> gpio31

GPIOCD_CH0 --> gpio32

Am I right?

Many Thanks

Gibbs
