DIN[3:0]/
GPIO[5:2]
20, 19, 18, 17 Input/Output, DIN[3:0] general-purpose pins can be individually configured as either inputs or
LVCMOS outputs; used to control and respond to various commands.
GPIO[1:0]
16, 15
Input/Output, General-purpose pins can be individually configured as either inputs or outputs; used
LVCMOS to control and respond to various commands.
BIDIRECTIONAL CONTROL BUS - I²C COMPATIBLE
SCL
