TMS320F28035: TZ Pin dual mapp trigger TZ event?

Joe Zhu

Hi Champion,

In F28035, if I change GPIO 12 and GPIO15 all to TZ1 function, I find TZ one shot and CBC cannot work now. So my question is if I use two different GPIO for one TZ function, does it can work normal? If work, is it be "or", "and" logic calculation?

Thanks!

Joe,

Please refer to section 4.5 "GPIO and Peripheral Multiplexing (MUX)" of the Systems Control and Interrupts User Guide. It describes the state of each signal with multiple mux locations.

"if more than one pin is configured as an input for the same peripheral, then the input to the peripheral will either default to a 0 or a 1"

Regards,
Cody
