| D18 and D19 share the I²C SCL·SDA functions; D24 and D25 share the ENC/FND CLK·DIO functions. The two functions of the same pin cannot be used simultaneously. D21~D23 use TIMER3 resources, and D26~D28 use TIMER1 resources. | D18 and D19 share the I²C SCL·SDA functions; D24 and D25 share the ENC/FND CLK·DIO functions.
