• Upon PLL lockup time timer overflow (time set by PLLS register) when the PLLCTL.PLLON bit is changed
• After the setup time inserted upon release of the IDLE2 mode is released (time set by the OSTS register)
Phase lock occurs at a given frequency following power application or immediately after the STOP mode is
released, and the time required for stabilization is the lockup time (frequency stabilization time). This state until
stabilization is called the lockup status, and the stabilized state is called the locked status.
The LOCKR register includes a LOCK bit that reflects the PLL frequency stabilization status.
This register is read-only, in 8-bit or 1-bit units.
Reset sets this register to 00H.
