Internal Pin Structure Table 15. Detailed Internal Pin Structure
Notes: 1. For information on resistors value, input/output levels, and drive capability, refer to
the Section DC Characteristics, page 181.
2. When the Two Wire controller is enabled, P
1
, P
2
, and P
3
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).
