Does another Pin I/O can set to GPIO mode?

Tinnagit Poojeerang

I'm a newbie for Hercules Developer.

I have some application that have to use 16bits parallel interface and I have no I/O pIn for another function

because the TMS570LS12x/11x Hercules Development Kit have 2 GPIO and 8 bit for each.

But they have many another Pin I/O function in that board but I have no information about changing the Pin I/O function

Does it can change Pin I/O function?

    Tinnagit,

    Most I/O pin pins support GPIO function. Take MIBSPI pins for example. All MIBSPI pins are in GPIO mode by default. To use them as MIBSPI function, you need to set the pins to "function" by writing to MIBSPI control registers. The only limitation is that those pins do no generate interrupt when in GPIO mode. Please check TRM for details.

    Thanks and regards,
