10 / 89 page W78E054D/W78E052D Data Sheet Publication Release Date: Jun 9, 2015 - 10 - Revision A13 Pin Description, continued SYMBOL TYPE DESCRIPTIONS P3.0 P3.7 I/O H PORT 3: Port 3 is a bi-directional I/O port with internal pull-ups. All bits have al- ternate functions, which are described below: RXD (P3.0): Serial Port 0 input TXD (P3.1): Serial Port 0 output INT0 (P3.2) : External Interrupt 0 INT1 (P3.3) : External Interrupt 1 T0 (P3.4) : Timer 0 External Input T1 (P3.5) : Timer 1 External Input WR (P3.6) : External Data Memory Write Strobe RD (P3.7) : External Data Memory Read Strobe P4.0 P4.3 I/O H PORT 4: Another bit-addressable bidirectional I/O port P4. P4.3 and P4.2 are alternative function pins. It can be used as general I/O port or external interrupt input sources ( INT2 / INT3 ). * Note: TYPE I: input, O: output, I/O: bi-directional, H: pull-high, L: pull-low, D: open drain. In application if MCU pins need external pull-up, it is recommended to add a pull-up resistor (10K ) between pin and power (V DD) instead of directly wiring pin to VDD for enhancing EMC. |
