8-Bit Microprocessor with OTP ROM
50 •
In most applications, pin R-OSCI and pin OSCO can be connected with a crystal or
ceramic resonator to generate oscillation. Figure 6-7 depicts such circuitry. Table 5
provides the recommended values of C1 and C2. Since each resonator has its own
attribute, user should refer to its specification for appropriate values of C1 and C2. RS,
a serial resistor, may be necessary for AT strip cut crystal or low frequency mode.
