question2
Q1 Create a program that will initialise Port2 bits 0 - 7 to outputs. Then in an endless loop perform the sequence of bit manipulations shown below. Your program should use bit masking operations. Here is an outline of the program in pseudo-code and with the first two bit manipulations done for you.
//initialise port 2 for output
//set all outputs to 0
while(1)
{
FIO2PIN |= 0x04 // set bit 2 on (0x04 = 00000100)
FIO2PIN &= ~0x04 // set bit 2 off
//set port2 bit 1 on
//set port2 bit 1 off
//set port2 bit 4 on
//set port2 bit 6 and bit 7 on
//set port2 bit 4 off
//set port2 bit 6 and bit 7 off
