MB90246A Series
(2) N-ch Open-drain Port
Port 6 is general-purpose I/O port having a combined function as resource input/output. Each pin can be switched
between resource and port bitwise.
Operation as output port
When a data is written into the PDR register, the data is latched to the output latch of PDR. When the output
latch value is set to “0”, the output transistor is turned on and the pin status is put into an “L” level output, while
writing “1” turns off the transistor and put the pin in a high-impedance status.
If the output pin is pulled-up, setting output latch value to “1” puts the pin in the pull-up status.
Reading the PDR register returns the pin value (same as the output latch value in the PDR).
Note: Execution of a read-modify-write instruction (e.g. bit set instruction) reads out the output latch value rather
than the pin value, leaving output latch that is not manipulated unchanged.
Operation as input port
Setting corresponding bit of the PDR register to “1” turns off the output transistor and the pin is put into a high-
impedance status.
Reading the PDR register returns the pin value (“0” or “1”).
