6 / 17 page No. 5997-6/17 LC662508A, 662512A, 662516A Continued from preceding page. Pin I/O Overview Output driver type Options State after a Standby mode reset operation P50 P51 P52 P53/INT2 P60/SI1/ML P61/S01/ P62/ SCK1/DT/ P63/PIN1 P70 P71 P72 P73 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 SI1 serial input pin and as the ML melody output pin. • P61 is also used as the SO1 serial output pin. • P62 is also used as the SCK1 serial clock pin and the DT dial tone output pin. • P63 is also used for the event count input to timer 1. Output ports P70 to P73 • Output in either 1-bit or 4-bit units. • The contents of the output latch are input by input instruction. I/O I/O O • Pch: Pull-up MOS type • Nch: Intermediate sink current type • Pch: CMOS type • Nch: Intermediate sink current type • Nch: +15V handling when OD option selected (P61 and P63 only) • Pch: Pu MOS • Nch: Intermediate sink current type • Pull-up MOS or Nch OD output • Output level on reset CMOS or Nch OD output (When the ML or DT output is used, select open-drain output and provide an external pull-up resistor.) Pull-up MOS or Nch OD output High or low (option) H H Hold mode: Output off Hold mode: Output off Hold mode: Output off Halt mode: Output retained Halt mode: Output retained Halt mode: Output retained P80 P81 P82 P83 Output ports P80 to P83 • Output in either 1-bit or 4-bit units. • The contents of the output latch are input by input instruction.
