9 / 27 page LC872G08A/06A/04A No.A1400-9/27 Continued from preceding page. Pin Name I/O Description Option Port 7 • 1-bit I/O port • I/O specifiable in 1-bit units • Pull-up resistors can be turned on and off in 1-bit units. • Pin functions P70: INT0 input / HOLD reset input / timer 0L capture input / watchdog timer output P70(AN8): AD converter input Interrupt acknowledge types Rising Falling Rising & Falling H level L level INT0 enable enable disable enable enable P70 I/O No RES I/O External reset input / internal reset output No CF1/XT1 I • Ceramic resonator or 32.768kHz crystal oscillator input pin • Pin function General-purpose input port No CF2/XT2 I/O • Ceramic resonator or 32.768kHz crystal oscillator output pin • Pin function General-purpose input port No Port Output Types The table below lists the types of port outputs and the presence/absence of a pull-up resistor. Data can be read into any input port even if it is in the output mode. Port Name Option selected in units of Option type Output type Pull-up resistor 1 CMOS Programmable (Note 1) P00 to P07 1 bit 2 Nch-open drain No 1 CMOS Programmable P10 to P17 1 bit 2 Nch-open drain Programmable 1 CMOS Programmable P20 to P21 1 bit 2 Nch-open drain Programmable P70 - No Nch-open drain Programmable Note 1: The control of the presence or absence of the programmable pull-up resistors for port 0 and the switching between low-and high-impedance pull-up connection is exercised in nibble (4-bit) units (P00 to 03 or P04 to 07). User Option Table Option Name Option Type Mask Version *1 Flash Version Option Selected in Units of Option Selection CMOS P00 to P07 1 bit Nch-open drain CMOS P10 to P17 1 bit Nch-open drain CMOS Port output form P20 to P21 1 bit Nch-open drain 00000h Program start address - × *2 - 01E00h Enable:Use Detect function - Disable:Not Used Low-voltage detection reset function Detect level - 7-level Power-on reset function Power-On reset level - 8-level *1: Mask option selection – No change possible after mask is completed. *2: Program start address of the mask version is 00000h. |
