C
bool PORT_PinLatchRead(PORT_PIN pin)
Summary
Read the value driven on the selected pin.
Description
This function reads the data driven on the selected I/O line/pin. The function does not sample the state of the hardware pin. It only returns the value that is written to output register. Refer to the PORT_PinRead() function if the state of the output pin needs to be read.
Precondition
The PORT_Initialize() function should have been called.
Parameters
Param | Description |
---|---|
pin | One of the IO pins from the enum PORT_PIN. |
Returns
- true - the present value in the output latch is a logic high.
- false - the present value in the output latch is a logic low.
Example
bool value; value = PORT_PinLatchRead(PORT_PIN_PB03);
Remarks
To read actual pin value, PIN_Read API should be used.
