Internal Pin Structure

Table 16. Detailed Internal Pin Structure

Notes:

1. For information on resistors value, input/output levels, and drive capability, refer to

the Section “DC Characteristics”, page 183.

2. When the Two Wire controller is enabled, P1, P2, and P3 transistors are disabled

allowing pseudo open-drain structure.

3. In Port 2, P

1 transistor is continuously driven when outputting a high level bit address

(A15:8).
