(0: input, 1: output) in backup mode they go to the input disabled high-impedance state. after a reset, they switch to the general-purpose input port function. 13 12 11 18 17 16 15 14 pc0 pc1 pc2 pc3 int1/pd0 int0/pd1 pd2 pd3 i/o o general-purpose output ports. note that pe0 has a shared function as the beep output, and that pe1 has a shared function as a d/a converter output port. since these ports are open drain ports, a resistor must be inserted between each port and vdd. at reset, they are set to the general-purpose output port function .the beep instruction is used to switch the beep/pe0 port between the general-purpose output port and the beep output functions. a beep instruction with b2 = 0 will set the beep/pe0 port to function as a general-purpose output port. if b2 is set to 1, the instruction will select the beep output function. bits b0 and b1 switch the frequency of the beep output. this ic supports two beep frequencies. * : when the pe0 port is set to function as the beep output, executing an output instruction for pe0 will only change the value of the internal output latch; it will have no effect on the output. the dac instruction is used to switch the dac/pe1 port between the general-purpose output port and dac output functions. these ports go to the high-impedance state in backup mode. that state is maintained until an output instruction, a beep instruction, or a dac instruction is executed. 19 18 beep/pe0 dac/pe1 i/o shared function pins used as either general-purpose i/o ports or a serial i/o port. note that there is a mask option that allows these pins to be used as n-channel open drain ports. when used as general-purpose i/o ports, the i/o direction can be switched in single pin units with the ios instruction. the ios instruction is used to switch the function between the general-purpose i/o port and the serial i/o port function. in backup mode, these pins go to the input disabled high-impedance state. after a reset, the general-purpose input port function is selected. 25 24 23 sck1/pk1 so1/pk2 si1/pk3 input with built-in pull-down resistor n-ch open-drain cmos push-pull/ n-ch open-drain cmos push-pull/ n-ch open-drain continued on next page. unbalanced cmos push-pull
