4.3 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 34.
2. When the 2-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).
