mode register 3 (PM3). When this pin is used as an input port, an on-chip pull-up resistor can be connected in 1-bit
units by using pull-up resistor option register 3 (PU3). This pin can also be used for external interrupt request input.
is the reset function. For the setting method for pin functions, see CHAPTER 15 OPTION BYTE.
The P32 pin is a 1-bit I/O port with an output latch. This pin can be set to the input or output mode by using port
The P32 pin is a Reset signal generation sets port 3 to the input mode.
The P34 pin is a 1-bit input-only port. This pin is also used as a RESET pin, and when the power is turned on, this
When P34 is used as an input port pin, connect the pull-up resistor.
Figures 4-5 and 4-6 show the block diagrams of port 3.
