however, avoid executing output instructions on these pins to ensure the accuracy of conversion. Also note that, during
AD conversion, rapidly changing signals should not be input on any pins near analog input pins.
P3 (P37 to P30) Port
The P3 port is an 8-bit input/output port that can be specified for input or output bitwise, and is shared with analog
The P3 port input/output control registers P3CR1 and P3CR2 are used to specify the function of each pin. After
To use each pin as a port output, set the corresponding bit in the P3CR1 to 1.
To use each pin as a port input, set the corresponding bit in the P3CR1 to 0 and then set the corresponding bit in
To use each pin as a key-on wakeup input, set the corresponding bit in the P3CR1 to 0 and then set the corresponding
To use each pin as an analog input, set the corresponding bit in the P3CR1 to 0 and then set the corresponding bit
When P3CR1=1, reading the P3DR returns the values of the respective output latches.
Any pins of the P3 port which are not used for analog input can be used as input/output ports. During AD conversion,
