I/O pin assignment
Notes (refer to
superscript numbers
placed after pin #):
1. This line is 5V-tolerant and can be interfaced to 5V CMOS devices directly.
2. This line can be mapped to serve as an RTS, W0 output, or CLOCK output line of
a serial port. The line can also be assigned to an I2C/SPI channel, or act as an
interface line of the Wi-Fi add-on module, keypad, or an LED control channel.
3. This line can serve as a CTS, W0&1 input, or CLOCK input line of a serial port.
