CONNECTIONS OF UNUSED PINS
Note 1.If a port input instruction (SZD, IAP0, IAP1, IAP2, IAP3) is executed when the output latch is 1, the supply voltage may be
increased in the instruction execution cycle by the through current.
Note 2.Do not select the CNTR0 input as the timer 1 count source. (W11 W10
≠11)
Note 3.Set the input of INT0 pin or INT1 pin to be disabled. (I13=0, I23=0)
Note 4.Set the output of the CNTR1 pin to be invalid. (W33=0)
(Note when connecting to VSS or VDD)
Connect the unused pins to VSS using the thickest wire at the shortest distance against noise.
