Oscillation circuit constants The oscillation circuit constants of XIN-XOUT, XCIN-XCOUT will depend on each product of Mask ROM version (L version, A version) and One-time PROM version. So that the product used for mass production obtains the stabilized operation clock on the user system and its condition, contact the resonator manufacturer and select the resonator and oscillation circuit constants. Be careful especially when range of voltage and temperature is wide. We recommend to design the circuit in consideration of the wiring pattern of the feed-back resistor, the dumping resistor and the load capacity in advance. We publish the reference-use oscillation circuit parameters in Renesas Technology home page. http://www.renesas.com/en/38000 Code : Difference of 3826 Group Rev. 1.00 Date : Sep.8, 2003 Page : 4 of 10 3.
