EM78P131A
8-Bit Microcontroller with OTP ROM
24 •
In most applications, pin OSCI and pin OSCO can be connected with a crystal or
ceramic resonator to generate oscillation. Fig. 5-12 depicts such circuit. The same
thing applies whether it is in the HXT mode or in the LXT mode.
In Fig. 5-12-1, when the connected resonator in OSCI and OSCO is used in
applications, R1 that is 1 MΩ needs to be shunted with resonator.
