Port Pin Register
Block Diagram
Notes: Pin register R/W
Performs open-drain control in output mode.
0: Operate as a standard output port in output mode.
1: Operate as an open-drain output port in output mode.
The setting has no meaning in input mode (output Hi-z).
The direction register (DDR) sets input or output mode
The pull-up resistor is disconnected in hardware standby or stop mode (SPL = 1) (high impedance).
This function is disabled when using an external bus. In this case, do not write to this register.
Analog Input Enable Register
Controls each port 5 pin as follows.
0: Port input mode
1: Analog input mode
Set to “1” by a reset.
