CHAPTER 4 I/O PORTS
4.6
Port 6
Port 6 is a general-purpose I/O port.
This section describes the port function when operating as general-purpose I/O port.
This section also describes the structure, pins, the block diagram of pins, and
associated registers of port 6.
■
Structure of Port 6
Port 6 comprises the following four elements:
•
General-purpose I/O pins (input pins P61-P60 for MB89F202/F202RA)
•
Port 6 data register (PDR6)
•
Port 6 data direction register (DDR6, not used in MB89F202/F202RA)
•
Port 6 pull-up setting register (PUL6)
■
Pins of Port 6
Port 6 has 2 I/O pins of CMOS input type (they are input only pins for MB89F202/F202RA).
Table 4.6-1 lists the pins of port 6.
*: P61 and P60 are general-purpose input port for MB89F202/F202RA.
For circuit type, see Section "1.7 Pin Functions Description " and "1.8 I/O Circuit Types ".
