Port 2, Output. Port 2 serves as the MSB for external addressing.  
P2.7 is A15 and P2.0 is A8. The device will automatically place the  
A10 (P2.2) MSB of an address on P2 for external ROM and RAM access.  
Although Port 2 can be accessed like an ordinary I/O port, the value  
stored on the Port 2 latch will never be seen on the pins (due to  
memory access). Therefore, writing to Port 2 in software is only  
useful for the instructions MOVX A, @Ri or MOVX @Ri, A. These  
instructions use the Port 2 internal latch to supply the external address  
MSB. In this case, the Port 2 latch value will be supplied as the  
address information.

Port 3, Input/Output. Port 3 functions as both an 8-bit, bidirectional  
I/O port and an alternate functional interface for External Interrupts,  
Serial Port 0, Timer 0 & 1 Inputs, RD and WR strobes. The reset  
condition of Port 3 is with all bits at logic 1. In this state, a weak  
pullup holds the port high. This condition also serves as an input  
mode, since any external circuit that writes to the port will overcome  
the weak pullup. When software writes a 0 to any port pin, the device  
will activate a strong pulldown that remains on until either a 1 is  
written or a reset occurs. Writing a 1 after the port has been at 0 will  
cause a strong transition driver to turn on, followed by a weaker  
sustaining pullup. Once the momentary strong driver turns off, the  
port once again becomes both the output high and input state. The  
alternate modes of Port 3 are outlined below:
