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
