Hi,
I was designing a PCB based on Delfino Microcontroller (TMS320F28335), and I had a simple question that can I use the higher 16-Bits of Delfino XINTF data bus as GPIOs, such that I would only need to use XINF in 16-Bit mode (accessing an SRAM in x16 Mode only).
Because in 16-Bit mode, XINTF would not be using the higher 16-Bits of XINTF, so am I free to use them as GPIO, or still must leave them unconnected ?
If used as GPIO, then during accessing data through SRAM, will these higher 16 bit data bus pins would retain their values written to them earlier as GPIOs ?
...
Thank you in advance for any answer.
