11 / 32 page LC87F06J2A No.A0432-11/32 Continued from preceding page. Pin Name I/O Function description Option SIO2 Port SI2P0 to SI2P3 I/O • 4-bit I/O port • I/O specifiable in 1-bit units • Other functions: SI2P0: SIO2 data output SI2P1: SIO2 data input, bus input/output SI2P2: SIO2 clock input/output SI2P3: SIO2 clock output No PWM0 O • PWM0 output port • General-purpose I/O available No PWM1 O • PWM1 output port • General-purpose I/O available No RES I Reset pin No XT1 I • Input terminal for 32.768kHz X'tal oscillation • Other functions: General-purpose input port Must be connected to VDD1 if not to be used. No XT2 I/O • Output terminal for 32.768kHz X'tal oscillation • Other functions: General-purpose I/O port Must be set for oscillation and kept open if not to be used. No CF1 I Ceramic resonator input pin No CF2 O Ceramic resonator output pin 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 Options selected in units of Option type Output type Pull-up resistor 1 CMOS Programmable (Note 1) P00 to P07 1 bit 2 N-channel open drain No 1 CMOS Programmable P10 to P17 P20 to P27 P30 to P36 PA0 to PA5 PC0 to PC7 1 bit 2 N-channel open drain Programmable 1 CMOS No PB0 to PB2 PB4, PB6 1 bit 2 N-channel open drain No PE0 to PE7 PF0 to PF7 - No CMOS Programmable P70 - No N-channel open drain Programmable P71 to P73 - No CMOS Programmable P80 to P87 - No N-channel open drain No SI2P0, SI2P2 SI2P3 PWM0, PWM1 - No CMOS No SI2P1 - No CMOS (when selected as ordinary port) N-channel open drain (when SIO2 data is selected) No XT1 - No Input only No XT2 - No Output for 32.768kHz crystal oscillator N-channel open drain (when in general-purpose output mode) No Note 1: Programmable pull-up resistors for port 0 are controlled in 4-bit units (P00 to P03, P04 to P07). |
