6.8. Oscillator Sources
Crystal oscillators are fitted on the board and used to supply the main/sub clock input to the Renesas microcontroller.
Table 6-12 details the oscillators that are fitted on this RSK:
Component
Crystal (X1) Fitted 20 MHz (HC49/4U package)
Crystal (X2) Not Fitted For test purpose only
Crystal (X3) Fitted 32.768 KHz (90 SMX package)

6.9. Reset Circuit
A reset control IC (i.e. RNA51957BFP) has been used to generate the reset signal required for the R8C/38C CPU.
Please check the hardware manual for the detailed reset requirements to ensure the reset circuit on the user’s board meets all the reset
timing requirements.
