(1) Port 0E
Note
P0EBPU3 P0EBPU2 P0EBPU1 P0EBPU0
If a key matrix is not used, whether or not a pull-up resistor is connected to port P0E can be specified in 1-
bit units by using the following registers of the register file
3
To disconnect the pull-up resistor in the output mode, clear the corresponding bit of the P0EBPU register.
