14 / 47 page  LC88FC2H0B www.onsemi.com 14 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 Output Type Pull-up Resistor P00 to P07 1 bit CMOS Programmable P10 to P17 P20 to P27 P30 to P37 P40 to P47 P50 to P57 P60 to P67 P70 to P77 PA0 to PA7 PB0 to PB6 Able to program special functions’output type from CMOS output or Nch-opendrain P60 to P67 P70 to p77 PD0 to PD5 PC2 CMOS PC0 N-channel open drain (32.768 kHz crystal oscillator input) None PC1 Nch-open drain (32.768k kHz crystal oscillator output) None PC3 CMOS (ceramic oscillator input) None PC4 CMOS (ceramic oscillator output) None * Make the following connection to minimize the noise input to the VDD1 pin and prolong the backup time. Be sure to electrically short the VSS1, VSS2, VSS3 and VSS4 pins. Example 1 : When data is being backed up in the HOLD mode, the H level signals to the output ports are fed by the backup capacitors. LSI Power supply VSS1 For buckup VSS2VSS3 VDD3 VDD2 VDD1 VDD4 VSS4 |
