CCS/TMS570LS0432: how to read NHET values

Is there a way to read NHET values using a get bit function similar to gioGetBit() for example?

Hello Brett,

If you use NHET pin as GIO, you can manipulate the pin using GIO APIs. For example:

/* Set high end timer GIO port hetPort pin direction to all output */
gioSetDirection(hetPORT1, 0xFFFFFFFF);

/* Toggle HET pin 0 */
gioSetPort(hetPORT1, gioGetPort(hetPORT1) ^ 0x00000001);

How does that toggle pin 0? why would I pass the value of the port in the second parameter?

Hello Brett,

gioSetPort(gioPORT_t *port, uint32 value) --> write a value to all pin of a given GIO port

The parameter "port " is the pointer to GIO port: portA, portB, or hetPORT1, hetPORT2.

gioGetPort(hetPORT1) ^ 0x00000001 --> read the value of hetPORT1, then XOR the value and 0x1 to invert value of pin0
