52-pin package I/O port

The 52-pin package members of the UPSD321xx devices have the same port pins as those

of the 80-pin package except:

● Port 0 (P0.0-P0.7, external address/data bus AD0-AD7)

● Port 2 (P2.0-P2.3, external address bus A8-A11)

● Port A (PA0-PA7)

● Port D (PD2)

● Bus control signal (RD,WR,PSEN,ALE)

● Pin 5 requires a pull-up resistor (2 kΩ for 3 V devices, 7.5 kΩ for 5 V devices) for all

devices, with or without USB function.
