7.
Normal stop mode:
As a power saving feature, normal stop mode disables and bypasses the PLL. Stop mode will then shut down the master clock,
recovery will take an extra cycle (to restart the clock), and t
clk
will resume at the input clock source rate.
ET = External Clock period, For an external crystal frequency of 8MHz, ET=125 ns.
