PRODUCTION DATA
| PIN | I/O | DESCRIPTION | |
|---|---|---|---|
| NAME | NO. | ||
| ADDR | 2 | I | Address input. Connect directly to VCCP or ground |
| GND | 8 | — | Ground |
| INT | 13 | O | Interrupt output. Connect to VCCI through a pull-up resistor |
| P0 | 4 | I/O | P-port input-output (push-pull design structure). At power on, P0 is configured as an input |
| P1 | 5 | I/O | P-port input-output (push-pull design structure). At power on, P1 is configured as an input |
| P2 | 6 | I/O | P-port input-output (push-pull design structure). At power on, P2 is configured as an input |
| P3 | 7 | I/O | P-port input-output (push-pull design structure). At power on, P3 is configured as an input |
| P4 | 9 | I/O | P-port input-output (push-pull design structure). At power on, P4 is configured as an input |
