11 / 62 page 11 µPD78001B(A), 78002B(A) A8 to A15 RD WR WAIT ASTB Input/ output Port 5 8-bit input/output port. LED can be driven directly. Input/output can be specified bit-wise. When used as an input port, pull-up resistor can be used by software. P50 to P57 P60 P61 P62 P63 P64 P65 P66 P67 Input/ output Port 6 8-bit input/output port. Input/output can be specified bit-wise. When used as an input port, pull-up resistor can be used by software. N-ch open-drain input/output port. On- chip pull-up resistor can be specified by mask option. LED can be driven directly. Pin Name I/O Function After Reset 3.1 PORT PINS (2/2) Dual- Function Pin Input Input Caution When pull-up resistors are not used (specified by mask option), the low-level input leak current increases with -200 µA (MAX.) under either of the following conditions. 1 When the external device expansion function is used and a low-level is input to the pin. 2 During the 3-clock period when a read instruction is executed on port 6 (P6) and the port mode register (PM6). |
