9 / 21 page LC866548/40/32/28/24A No.6700-9/21 Pin Name I/O Function Description Option XT2/P75 O •Output pin for 32.768kHz crystal oscillation •Other function P75 for input port •In case of non use, At using as oscillator, should be left opened. At using as a port, connect to VDD1. CF1 I Input pin for ceramic resonator oscillation CF2 O Output pin for ceramic resonator oscillation * All of port options (except pull-up resistor of port 0) can be specified in bit unit. * A state of pins at reset Pin name Input/output mode A state of pull-up resistor specified at pull-up option Port 0 Input Fixed pull-up resistor OFF Ports 1, 3 Input Programmable pull-up resistor OFF S0/T0 to S15/T15 P channel Transistor OFF S16 to S51 P channel Transistor OFF *1 Connect like the following figure to reduce noise into a VDD1 terminal. • Shorted the VSS1 terminal to the VSS2 terminal and to make the back-up time long. Power Supply LSI VDD1 Back-up capacitor VDD2 VDD3 VSS2 VSS1 VDD4 VFD powers |
