Section 4 Clock Pulse Generator (CPG)
4.7
4.7.1
In the case of using a crystal resonator, please wait longer than the oscillation stabilizing time at
the following cases, to keep the oscillation stabilizing time of the on-chip crystal oscillator (In the
case of inputting an external clock input, it is not necessary).
• Power on
• Canceling software standby mode or deep standby mode by using the RES or MRES pin
• Changing from halting oscillation to running oscillation by power-on reset or register setting
4.7.2
In clock mode 0 or 1 the clock input on EXTAL, in clock mode 2 the clock input on CKIO, and in
clock mode 3 the clock input on USB_X1 is supplied to the PLL circuit. So, regardless of whether
using a crystal resonator or inputting an external clock from EXTAL (clock mode 0 and 1) or
USB_X1 (clock mode 1 and 3), please wait longer than the oscillation stabilizing time at the
following cases, to keep the oscillation stabilizing time of the PLL circuit.
• Power on (in the case of using the crystal resonator)/start inputting external clock (in the case
• Canceling software standby mode or deep standby mode by using the RES or MRES pin
• Changing the multiplication ratio of the PLL circuit by power-on reset from RES pin
[Remarks]
The oscillation stabilizing time is kept by the counter running in the LSI at the following cases.
• Canceling software standby mode or deep standby mode by using the RES or MRES pin
