R OPTION FUNCTION FOR P0 (INPUT ONLY)
There is some difference between I/O pin's and input pin's R-option function. When input pin's R-option mask
option is selected, there are two pin's mask options (none, pull-up) can be slected. When the R-option control
signal is low, the weak PMOS will turn on and pin's pull-up resistor will turn off (this pin's mask option selects
pull-up). In this case, the input data is low when this pad connects a 560K
external resistor to GND, and the
input data is high when this pad is open outside. When the R-option control signal is high, the weak PMOS
will trun off and pin's pull-down resistor will trun on. In sleep mode, user must disable R-option function for
power saving. The R-option control signal is also decided by P20.3.
