Need help with firmware code..
I am trying to write a program to initialize General purpose Input Output ports.
The microcontroller I need to initialize the ports on - is a C8051F330 chip.

I need to write the program in C++.
So far This is what I have .I am stuck and not sure if this is correct or wrong. Any help would mean a lot . Thank you.
P0 = 0x0F ; write to port
var = P0 ; reads the port into a char variable
Pin0 = 1 ; set port 0 pin 0 bit to 1
bit = Pin0 ; reads port 0 pin 0 into bit
P0MDIN = 0xFF ; setting to 1's
P0MDOUT = 0xFF ; push pull
P0SKIP = 0xFF ; setting port 0 to skip
XBR1 |= 0X40 ; setting xbare bit in XBR1 register
