10 / 23 page LC875G32A/24A/16A/08A No.8299-10/23 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 P27 1-bit 2 Nch-open drain Programmable 1 CMOS Programmable P30 to P36 1-bit 2 Nch-open drain Programmable P70 - No Nch-open drain Programmable P71 to P73 - No CMOS Programmable PWM0, PWM1 - No CMOS No XT1 - No Output for 32.768kHz crystal oscillator (Input only) No XT2 - No Input for 32.768kHz crystal oscillator (Nch-open drain when in general-purpose output mode) No Note 1: Programmable pull-up resistor of Port 0 is specified in nibble units (P00 to P03, P04 to P07). Note: To reduce VDD signal noise and to increase the duration of the backup battery supply, VSS1, VSS2, and VSS3 should connect to each other and they should also be grounded. Example 1: During backup in hold mode, port output ‘H’ level is supplied from the back-up capacitor. Example 2: During backup in hold mode, output is not held high and its value in unsettled.
