variables.
IO_Write
Void IO_Write (IO_Port Port_Val3,IO_Pin Pin_Val3,
IO_Write_Data Data_Val)
Writes the data into the port pins.
Selects the port name.
IO_PORT_V
V= A,B,... The port name as per datasheet.
Selects port pin number. Here you can select more than
one pin number by ‘OR’ing them.
IO_PIN_W
W= 0 to 7.
Selects the data to be written in the port pin.
IO_DATA_HIGH
Writes logic high in port pin
IO_DATA_LOW
Writes logic low in port pin
IO_DATA_TOGGLE
Toggles port pin
