CFG_DiInterruptSupportedChannel gets the DI channels which support interrupt function.
| Type | INT8U array |
| Length | 1 byte for one port, 1 bit for one channel. |
| Access type | Read |
| Value | Each bit
in the byte array represents one channel. If the bit returns "1", means the corresponding channel supports DI Interrupt function, otherwise it doesn't support. For example, for a 2-port DI device, the size of the array is 2; when the returned array is [2,5], which means channel1 in port0, channel0 and channel2 in port1, support this function. |
