Function Descriptions
EXAMPLE:
The following C program shows the use of the I/O functions.
Program Description:
This program, written for the ST72F521 device, configures all Port D pins in push-pull output
mode. The D5 and D7 port pins are put into logic high state. The port register is read and the
data is compared with the written data. If there is any mismatch between the data read and
data written, the control goes into a ‘while’ loop.
It then configures Port C (C3 & C4) in floating input mode. The C3 and C4 port pins are put into
logic high state by the external input. Then, port C is read. The read value is compared with
expected value, i.e.,0x18. If there is any mismatch between the data read and expected data,
the control goes into a ‘while’ loop.
