Section 4 Clock Pulse Generator (CPG)
4.6.3
Since various characteristics related to the resonator are closely linked to the user's board design,
thorough evaluation is necessary on the user's part, using the resonator connection examples
shown in this section as a guide. As the parameters for the oscillation circuit will depend on the
floating capacitance of the resonator and the user board, the parameters should be determined in
consultation with the resonator manufacturer. The design must ensure that a voltage exceeding the
maximum rating is not applied to the resonator pin.
4.6.4
In the PLLVcc and PLLVss connection pattern for the PLL, signal lines from the board power
supply pins must be as short as possible and pattern width must be as wide as possible to reduce
inductive interference.
In clock operating mode 3, the EXTAL pin is pulled up and the XTAL pin is left open.
Since the analog power supply pins of the PLL are sensitive to the noise, the system may
malfunction due to inductive interference at the other power supply pins. To prevent such
malfunction, the analog power supply pin Vcc and the digital power supply pins VccR and PVcc
should not supply the same resources on the board if at all possible.
4.6.5
If the multiplication rate is changed by the frequency control register (FRQCR) during transfer by
the DMAC, the DMAC stops its operation without waiting for the completion of the transfer.
Thus, the DMA transfer is not guaranteed. Therefore, when changing the multiplication rate with
the frequency control register (FRQCR), wait for the completion of the DMA transfer or stop the
DMA transfer to change the setting of the frequency control register (FRQCR).
