6 / 28 page Pin Function Overview No. 5489-6/28 LC66P5316 Pin I/O Overview Output driver type Options State after a Standby mode reset operation P00/D0 P01/D1 P02/D2 P03/D3 P10/D4 P11/D5 P12/D6 P13/D7 P20/SI0/A0 P21/SO0/A1 P22/SCK0/ A2 P23/INT0/A3 P30/INT1/A4 P31/POUT0/ A5 P32/POUT1/ A6 P33/HOLD P40/INV0I/ A7 P41/INV0O/ A8 P42/INV1I/ A9 P43/INV1O/ A10 I/O ports P00 to P03 • Input or output in 4-bit or 1-bit units • P00 to P03 support the halt mode control function (This function can be specified in bit units.) • Used as data pins in EPROM mode I/O ports P10 to P13 • Input or output in 4-bit or 1-bit units • Used as data pins in EPROM mode I/O ports P20 to P23 • Input or output in 4-bit or 1-bit units • P20 is also used as the serial input SI0 pin. • P21 is also used as the serial output SO0 pin. • P22 is also used as the serial clock SCK0 pin. • P23 is also used as the INT0 interrupt request pin, and also as the timer 0 event counting and pulse width measurement input. • Used as address pins in EPROM mode I/O ports P30 to P32 • Input or output in 3-bit or 1-bit units • P30 is also used as the INT1 interrupt request. • P31 is also used for the square wave output from timer 0. • P32 is also used for the square wave and PWM output from timer 1. • P31 and P32 also support 3-state outputs. • Used as address pins in EPROM mode Hold mode control input • Hold mode is set up by the HOLD instruction when HOLD is low. • In hold mode, the CPU is restarted by setting HOLD to the high level. • This pin can be used as input port P33 along with P30 to P32. • When the P33/HOLD pin is at the low level, the CPU will not be reset by a low level on the RES pin. Therefore, applications must not set P33/HOLD low when power is first applied. I/O ports P40 to P43 • Input or output in 4-bit or 1-bit units • Input or output in 8-bit units when used in conjunction with P50 to P53. • Can be used for output of 8-bit ROM data when used in conjunction with P50 to P53. • Dedicated inverter circuit (option) • Used as address pins in EPROM mode I/O I/O I/O I/O I I/O • Pch: Pull-up MOS type • Nch: Intermediate sink current type • Pch: Pull-up MOS type • Nch: Intermediate sink current type • Pch: CMOS type • Nch: Intermediate sink current type • Pch: CMOS type • Nch: Intermediate sink current type • Pch: Pull-up MOS type • CMOS type when the inverter circuit option is selected • Nch: Intermediate sink current type • Pull-up MOS or Nch OD output • Output level on reset • Pull-up MOS or Nch OD output • Output level on reset CMOS or Nch OD output CMOS or Nch OD output • Pull-up MOS or Nch OD output • Output level on reset • Inverter circuit High or low (option) High or low (option) H H • High or low (option) • Inverter I/O is set to the output off state. Hold mode: Output off Hold mode: Output off Hold mode: Output off Hold mode: Output off Hold mode: Port output off, inverter output off Halt mode: Port output retained, inverter output continues Hold mode: Output off Halt mode: Output retained Halt mode: Output retained Halt mode: Output retained Continued on next page. |
