Notes
- Pins 2, 3, 4, 5, 6: Have internal 100 kΩ series resistors; output driving capability is limited and should connect to CMOS inputs only.
- Pin 11 (VDD): Do not use for supply to external circuits; reserved for pull-ups only if required.
- Pin 12 (ON/OFF): See Electrical Specifications for threshold voltage details and Power Management notes.
- Pin 13 (VCC): Maximum rise-time requirements apply; see Electrical Specifications.
- Pin 22 (RESET): Has internal 100 kΩ pull-up resistor (no series resistor).
- UART Mode: Pins 5 (TXD) and 6 (RXD) used for serial data; pins 2 and 3 for flow control (optional).
- Synchronous Mode: Pins 5 (SCL) and 6 (SDA) used for serial data; pins 2 and 3 select operation mode (active low).
