2 | 5us delay, release the always-on domain reset, and clocks generated in always-on domain. And release the reset source on dom_sys_top. |
3 | Power down the PLL with 2us time interval |
4 | After the PLL power-down has been finished, wait 200us for PLL locking. |
5 | 64 cycles of oscillator clock delay, release the system Clock and Reset Generator (CRG)'s reset to prepare the clock for system |
6 | 64 cycles of oscillator clock delay, and release the system bus reset |
