Table 21 shows, which of the EEPROM pins connect to
which pogo pad of utility block 1. The there used abbrevi-
ations for the functional assignment of the pins have the
following meaning:
• SCL is the pin for the Serial CLock.
• SDA is the pin for Serial DAta.
• A1 and A2 are the Address inputs pins, A0 is a no
connect pin.
• VSS is the ground pin
• WPI is the test input pin.
• VCC is the supply voltage pin.
