5 Pin Addresses
Pin addresses are encoded in two bytes of the format 0PPPPPPP 00000PPP, where the first
byte encodes the less significant 7 bits of the pin number, and the second byte encodes the
more significant bits of the pin number. On devices with less than 128 pins, the second byte
is always 0x00.
The second byte for pin numbers below 128 is therefore 0x00. Examples for physical pin
addresses are listed in table 8.
