Function Descriptions
Table 166. IO_Input
Notes:
– You can use this function to configure pins as floating input, when the pins are used as ADC
– If you want to select external interrupt, you should use the “EnableInterrupts” macro after this
Caution:
– Alternate function must not be activated, while the pin is configured as input with interrupt,
– Input pull-up configuration can cause an unexpected value at the input of the alternate pe-

IO_Input
Void IO_Input (IO_Input_Mode Input_Val, IO_Port
Port_Val1, IO_Pin Pin_Val1)
Configures the I/O ports in input mode. You can also se-
lect external interrupt function, by selecting the corre-
sponding input parameters. Refer to the datasheet to
select the input mode and input port name.
Select the input mode, by selecting one of the below pa-
rameters.
IO_FLOATING
Selects floating input mode.
IO_FLOATING_IT
Selects floating input mode, with external interrupt.
IO_PULL_UP
Selects pull-up input mode.
IO_PULL_UP_IT
Selects pull-up input mode, with external interrupt.
Selects the port name.
IO_PORT_X
X= A,B,... The port name has to selected with reference to
the datasheet.
Selects port pin number. You can select more than one pin
number, by ‘OR’ing them.
