Power on Reset
When applying voltage to the MICRF505 a power on
reset state is entered. During the time period of
power
considered to be in an unknown state and the user
should wait until completed (See Table 6). The
power on reset timing given in Table 6 is covering all
conditions and should be treated as a maximum
delay time. In some application it might be beneficial
to minimize the power on reset time. In these cases
we recommend to follow below procedure:
