LC662512A Datenblatt(HTML) 6 Page - Sanyo Semicon Device |
6 / 25 page Continued from preceding page. Note: Pull-up MOS type: The output circuit includes a MOS transistor that pulls the pin up to VDD. CMOS output: Complementary output. OD output: Open-drain output. No. 5483-6/25 LC662304A, 662306A, 662308A, 662312A, 662316A Pin I/O Overview Output driver type Options State after a Standby mode reset operation P50 P51 P52 P53/INT2 P60/ML P61 P62/DT P63/PIN1 PC2 PC3 PD0/INV2I PD1/INV2O PD2/INV3I PD3/INV4O PE0 PE1 OSC1 OSC2 RES TEST VDD VSS I/O ports P50 to P53 • Input or output in 4-bit or 1-bit units • Input or output in 8-bit units when used in conjunction with P40 to P43. • Can be used for output of 8-bit ROM data when used in conjunction with P40 to P43. • P53 is also used as the INT2 interrupt request. I/O ports P60 to P63 • Input or output in 4-bit or 1-bit units • P60 is also used as the melody output ML pin. • P62 is also used as the tone output DT pin. • P63 is also used for the event count input to timer 1. I/O ports PC2 to PC3 Output in 2-bit or 1-bit units Dedicated input ports PD0 to PD3 Dedicated inverter circuits (option) Dedicated input ports System clock oscillator connections When an external clock is used, leave OSC2 open and connect the clock signal to OSC1. System reset input When the P33/HOLD pin is at the high level, a low level input to the RES pin will initialize the CPU. CPU test pin This pin must be connected to VSS during normal operation.
